This instruction is used to read 8‐bits of data to the CGRAM or DDRAM at the current address counter. After the read is
complete, the address is automatically incremented or decremented by 1 according to the Entry Mode.
The Set CGRAM Address or Set DDRAM Address Instruction must be executed before this instruction can be performed,
otherwise the first Read Data will not be valid.
MPU Interface
When DL is set for 8‐bit mode, the display interfaces with the MPU with DB7..DB0 (DB7 is the MSB).
When DL is set for 4‐bit mode, the display interfaces with the MPU with only DB7..DB4 (DB7 is the MSB). Each
instruction must be sent in two operations, the 4 high‐order bits first, followed by the 4 low‐order bits. The Busy Flag
must be checked after completion of the entire 8‐bit instruction.
