Note:
Transfer synchronization function for an 8-bit bus interface
The HD66766R supports the transfer synchronization function which resets the upper/lower
counter to count upper/lower 8-bit data transfer in the 8-bit bus interface. Noise causing transfer
mismatch between the eight upper and lower bits can be corrected by a reset triggered by
consecutively writing a “00”H instruction four times. The next transfer starts from the upper
eight bits. Executing synchronization function periodically can recover any runaway in the display
system
