11-2. T6963 controller data
11-2.1 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 ).
