12-2 T6963C controller
12-2.1 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 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
Bolymin, Inc.
◆◆◆
(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
(Note)
(b)The case of 2 data
When sending more than two data, the last datum (or last two data)is valid.

The position of the cursor is specified by X ADRS and Y ADRS. The cursor position can only

(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

The display mode is defined by this command. The display mode does not change until the
next command is sent. The logical OR, EXOR, AND of text or graphic 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.
(Example)
(Note)Attribute functions can only be applied to text display, since the attribute data is placed in the
graphic RAM area.
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

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.
