goes to next address. When Y address goes to 33H, next address is 00H, too.

Remark Data of X address = 0CH : b7 to b4 are data, b3 to b0 are don't care.

When 1/53 duty and using 1/40 duty are used, the RAM addresses and the common pins used are as follows.

Note If address incrementation is set when 1/40 duty is used, the X address value following 0CH is 00H. At the

same time the Y address is incremented by 1. The Y address value following 12H is 1AH, and the value
