CGRAM Address Set

range from 00H to 1FH (32 addresses) (Table 15).
Once the CGRAM address is set, data in the CGRAM can be accessed consecutively since the address
counter is automatically incremented or decremented according to the I/D bit setting after each access.
The CGRAM address cannot be set during sleep or standby mode.
