S6A0092
ADDRESS COUNTER (AC)
Address Counter (AC) in S6A0092 stores DDRAM / CGRAM / ICONRAM address. After writing into or reading from
DDRAM / CGRAM / ICONRAM, AC is automatically increased by 1. The address counter is only one and stores the
address among DDRAM / CGRAM / ICONRAM.
DISPLAY DATA RAM (DDRAM)
DDRAM stores display data of maximum 64 x 8 bits (Max. 64 characters). DDRAM address is set in the address
counter (AC) as a hexadecimal number.
