10. Display Control Instruction
The LCD Module has built in a T6963C 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 K byte 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.
Bolymin, Inc.
◆◆◆
(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 T6963C 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 T6963C during this period, the
T6963C 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.
Bolymin, Inc.
◆◆◆
(2) Setting date
When using the T6963C, first set the data, then set the command.
Procedure for sending a command
(a)The case of 1 date
(b)The case of 2 data
(Note) When sending more than two data, the last datum (or last two data) is
valid.

position can only be moved by this command. Data read/write from the MPU
never changes the cursor pointer. X ADRS and Y ADRS are specified as
follows.

(2) Set Offset Register
The offset register is used to determine the external character generator RAM
area.
The T6963C has a 16-bit address bus as follows.
T6963C 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.

Attribute function
The attribute operations are Reverse display, Character blink and Inhibit. The
attribute data is written into the graphic area which was defined by the Set Control
Word command. Only text display is possible in Attribute Function mode; graphic
display is 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 graphic area.
The Attribute function is defined as follows.

The command is convenient for sending a full screen of data from the external
display RAM. After setting Auto mode, a Data Write (or Read) command is need 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 T6963C 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 flowchart.
