(1)Set Cursor Pointer
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.
X ADRS 00H to 4FH (lower 7 bits are valid)
Y ADRS 00H to 1FH (lower 5 bits are valid)
Single-Scan
X ADRS 00 to 4FH
(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”
