(3)RAM control
Writer mode
Fig.3
LCD RAM can be written or read with control signal. The RAMEN pin can select a RAM which can be read or
write . The RAMADS pin can select whether RAMD(3:0) are data or address of RAM. At the address mode ,
RAMADS is low and user should sent address three times. From address (11:8) to address (3:0). Then it will go
into data mode when RAMADS is high. In data mode , user can sent one or more nibble data which address can
be increased by internal counter.
Once the RAMEN pin is high, the RAM can not read and write.
* This specification are subject to be changed without notice.
