DDRAM Address Set
The DDRAM address set instruction (Figure 19) includes the A bits.
AAAAAAA:
Used for setting the DDRAM address in the address counter (AC). The DDRAM addresses
range from 00H to 4BH (60 addresses) (Table 16).
Once the DDRAM address is set, data in the DDRAM can be accessed consecutively since the address
counter is automatically incremented or decremented according to the I/D bit setting after each access.
Here, invalid addresses are automatically skipped. The DDRAM address cannot be set during sleep or
standby mode.
