Setting registers
(1)Set Cursor Pointer
(2)Set Offset Register
The position of the cursor is specified by X ADRS and Y ADRS. The cursor 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.
Single-Scan
X ADRS 00 to 4FH
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
X ADRS 00H to 4FH (lower 7 bits are valid)
Y ADRS 00H to 1FH (lower 5 bits are valid)
