2-4. Manual Configuration Mode
When OPL3-SA3 is in the Wait for Key state, it can be changed to the Manual Configuration mode
by sending the following YAMAHA key to Address_Port. The Manual Configuration mode is used
for downloading the resource data to EEPROM and internal SRAM, setting up the OPL3-SA3
without PnP protocol.
YAMAHA Key:
B1h, D8h, 6Ch, 36h, 9Bh, 4Dh, A6h, D3h,
69h, B4h, 5Ah, ADh, D6h, EBh, 75h, BAh,
DDh, EEh, F7h, 7Bh, 3Dh, 9Eh, CFh, 67h,
33h, 19h, 8Ch, 46h, A3h, 51h, A8h, 54h
In the Manual Configuration mode, PnP registers can be accessed by the host without PnP protocol.
Right after OPL3-SA3 is switched to the Manual Configuration mode, set “81h” in CSN register
automatically to put OPL3-SA3 in ‘Sleep’ State. And when “81h” is written to Wake [CSN], it
becomes possible to access to Configuration register of each logical device from the host.
To return from the Manual Configuration mode to PnP auto-configuration mode, the Wait for Key
command should be sent.
Note :
The Manual Configuration mode can not be used in the system with more than one OPL3-SA3’s card
installed in the ISA slot.

YMF715E
3. Download Resource data
When OPL3-SA3 is in the Configuration state, the host can download the resources data to EEPROM
and internal SRAM via 20h: Resource Data Write. To switch OPL3-SA3 into configuration mode,
there are two methods.
First method is to use the normal PnP protocol. After CSN was assigned for all ISA cards by PnP software, get CSN from CM (configuration manager) and write the CSN to Wake [CSN], then OPL3-SA3
switches into configuration state.
Second method is to use the YAMAHA Key sequence which is described in the Manual Configuration
mode section. After OPL3-SA3 detects YAMAHA key, OPL3-SA3 switches into the Sleep state.
Writing “81h” to Wake [CSN] register changes OPL3-SA3 into Configuration state.
After OPL3-SA3 switches into the Configuration state, download the Resource data to EEPROM and
internal SRAM by using following sequence.
1.
Write “01h”(RDWE bit = “1”) to 21h: Resource Data Write Enable register to reset
internal address counter and to enable downloading the data.
2.
Write Resource data to 20h: Resource Data Write register until downloading data is
completed.
3.
Write “00h” to 21h: Resource Data Write Enable register to disable downloading .
4. External EEPROM
The resource data information of OPL3-SA3 used for PnP auto configuration is stored in external
EEPROM. And either 256 x 16-bit EEPROM or 128 x 16-bit EEPROM, such as 93C55, 93C56,
93C65, 93C66 should be used.
5. Hardware Volume Control
5-1. Hardware Volume up/down/mute Control
Two digital input pins; /VOLUP and /VOLDW can control the master volume of OPL3-SA3.
When /VOLUP is low level, register value of master volume is decremented(-1). When the value
reaches to “00h”(max.0dB), the input signal will not be effective.
When /VOLDW is low level, register value of master volume is incremented(+1). When the value
reaches to “0Fh”(min.-30dB), the input signal will not be effective.
When both of the /VOLUP and /VOLDW are low level simultaneously, volume is muted. When either
/VOLUP or /VOLDW is low level, the previous value becomes effective, and volume is no mute.
5-2. Hardware Volume Interrupt
If configured VEN(Hardware Volume Enable)=1, SA3 Control Register, index 0Ah, D7 bit, when one
of the hardware volume control pins /VOLUP or /VOLDW is asserted or when both are asserted to
request mute, interrupt will be posted in the interrupt channel specified in SA3 Control Register, index
17h, IRQ-A MV or IRQ-B MV bit.
Note that when the muting is in effect, the subsequent mute requests which does not change any
register contents will generate interrrupts. The ignored UP/DOWN requests (UP requests with 0dB
Volume attn., DOWN requests with -30dB) will not generate interrupts.
This bit is cleared upon host’s reading the Master Volume Lch register, SA3 Control Register, index
07h.

6. DAC interface
OPL3-SA3 supports two types of DAC interface format. One is the conventional DAC interface format
(very common for the consumer audio product) for OPL4-ML/ML2. Another is the I 2S format for
Zoomed Video port. These two types of the formats are shown in the following Fig.6-1, 2.

7. 3D Enhanced Control
OPL3-SA3 integrates the 3D enhanced controller including all the analog components in conventional
systems. Wide, bass, and treble controls are available via SA3 control register, index 14h, 15h, 16h.
One of the four 3D Enhancement modes can be selected according to the frequency response of the
speaker. These are controlled by SA3 control register, index 02h D5, D4 bit (YMODE1-0).

8-1. Partial Power Down Mode
Functional blocks comprising OPL3-SA3 which are shown in Fig.8-1, are designed so they can be
disabled independent of each other. SA3 control register, index 12h and 13h, implements these
controls (see section 9-1-5).
, blocks in the above diagram show those that can be disabled/enabled. Note, however,
the OPL3-SA3 dissipates more power with all these blocks “partial power down”ed than that can be
achieved in “power save mode 2”.
In this mode, master volume is not muted, so all analog input sources and enabled digital sources (i.e.
FM, SB, WSS etc.) can be heard.
Note :
AUX2 inputs are exceptions in this regard since setting FM-DAC at index 13h of SA3 Control
Register inhibits the inputs altogether.
8-2. Power Save Mode
SA3 control register, index 01h, PSV and PDX bits, implement these controls.
Clock generator can be controlled under either two options.
(i) Power Save Mode 1 (Clock Generator Control : Disabled (stop))
(PSV=PDX=1)
It is necessary to take some time before clock oscillation to stabilize. Power dissipation of digital
portion becomes about 100uA(typ.), and that of analog portion becomes about 5mA(typ.).
(ii) Power Save Mode 2 (Clock Generator Control : Enabled (crystals keep on oscillating))
(PSV=1, PDX=0)
Leaving power save mode gets the OPL3-SA3 back into function instantly. Power dissipation of
digital portion becomes about 10mA(typ.), and that of analog portion becomes about 5mA(typ.).
In these power save modes, the OUTL/R pins will keep the VREF voltage. During these modes,
master volume is automatically muted, so all audio sources can not heard. After resuming from these
modes, master volume is still muted.
8-3. Global Power Down Mode
(PDN=PDX=1)
This mode is to minimize power dissipation by stopping all the function of OPL3-SA3. It is
necessary to take some time before clock oscillation to stabilize. Total dissipation becomes about
10uA(typ.).
VREF voltage slowly decays to ground on transition into this mode, and quickly returns to VREF on
transition from this mode. During this mode, master volume is automatically muted, so all audio
sources can not heard. After resuming from this mode, master volume is still muted.

YMF715E
8-4. Suspend/Resume Mode
There is no “read only” or “hidden state” registers in OPL3-SA3. This means you can always read
and save these values before power off and can set those values back in registers after reset or power
on to achieve the suspend/resume capability.

2) In the power save modes 1, 2, the OUTL/R pins will keep the VREF voltage. In the power down
mode, VREF voltage slowly decays to ground on transition into this mode, and quickly returns to
VREF on transition from this mode. During these modes (power save/down), master volume is
automatically muted, so all audio sources cannot be heard. After resuming these modes, master
volume is still muted.
3) The Joystick portion must be re-initialized by writing any value to the Joystick port after resuming
from the power down/save mode.

There are four devices (WSS (Windows Sound System CODEC), SB (Sound Blaster
compatible portion), OPL3, MPU (MPU401)) that can be an interrupt source. This
register specifies what interrupt source is routed to two physical interrupt (IRQA and
IRQB) of OPL3-SA3. The device written to ”1” is assigned to the corresponding interrupt.
And by writing all “1” to upper or lower half byte, it is possible to share all interrupt
sources to a single physical interrupt line.

In case of loading the value, both high and low bytes are loaded to internal DMA counter
when the high byte is written. The value set to this register is “(the number of transfer
