11-2 SAP1024B controller data
11-2.1 Display control instruction
The LCD Module has built in a SAP1024B
LSI controller, It has an 8-bit parallel
data bus and control lines for writing or reading through an MPU interface, it has a
128-word character generator ROM ( refer to Table 1. ), which can control an external
display RAM of up to 8K bytes. Allocation of text, graphics and external character
generator RAM can be made easily and the display window can be moved freely within
the allocated memory range.
•RAM Interface
The external RAM is used to store display data( text, graphic and external CG
data ). It can be freely allocated to the memory area( 8 Kbyte max ).

◆◆◆
(Note 1) It is necessary to check STA0 and STA1 at the same time.
There is a possibility of erroneous operation due to a hardware interrupt.
(Note 2) For most modes STA0/STA1 are used as a status check.
(Note 3) STA2 and STA3 are valid in Auto mode; STA0 and STA1 are invalid.
Status Checking flow
(a)
(b)
(Note 4) When using the MSB=0 command, a Status Read must be performed.
If a status check is not carried out, the SAP1024B cannot operate normally,
even after a delay time.
The hardware interrupt occurs during the address calculation period (at the
end of each line).
If a MSB=0 command is sent to the SAP1024B during this period, the
SAP1024B enters Wait status.
If a status check is not carried out in this state before the next command is
sent, there is the possibility that the command or data date will not be
received.

(2)Set Offset Register
The offset register is used to determine the external character generator RAM area.
The SAP1024B has a 16-bit address bus as follows.
SAP1024B assign External character generator, when character code set 80H TO
FFH in using internal character generator. Character code 00H to 80H assign
External character generator, when External generator mode.
The senior five bits define the start address in external memory of the CG RAM
area. The next eight bits represent the character code of the character. In internal CG
ROM, character codes 00H to 7FH represent the predefined “internal” CG ROM
characters, and codes 80H to FFH represent the user’s own “external” characters. In
external CG ROM mode, all 256 codes from 00H to FFH can be used to represent
the user’s own characters. The three least significant bits indicate one of the eight
rows of eight dots that define the character’s shape.

display can be displayed. In Internal Character Generator mode, character codes
00H to 7FH are assigned to the built-in character generator ROM. The character
codes 80H to FFH are automatically assigned to the external character generator
RAM.

automatically disabled. However, the Display Mode command must be used to turn
both Text and Graphic on in order for the Attribute function to be available.
The attribute data for each character in the text area is written to the same address in the

The command is convenient for sending a full screen of data from the external

not be sent between each datum. A Data Auto Write (or Read) command must be
sent after a Set Address Pointer command. After this command, the address pointer
is automatically incremented by 1 after each datum. In Auto mode, the SAP1024B
cannot accept any other commands.
The Auto Reset command must be sent to the T69963C after all data has been sent,
to clear Auto mode.
(Note)A Status check for Auto mode
(STA2, STA3 should be checked between sending of each datum. Auto Reset
should be performed after checking STA3=1 (STA2=1.) Refer to the following
