DDRAM Address Set
The DDRAM address set instruction (Figure 20) includes the A (ADD), IRE, and KF bits.
AAAAAAA:
Used for setting the DDRAM address into the address counter (AC). The DDRAM addresses
range from “00”H to “4B”H (60 addresses) (Table 21).
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 the sleep or
standby mode.
