SEGRAM display data
RAM Data (RF)
WD7-0 :
Write 8-bit data to the DDRAM and CGRAM, and lower 2-bit data to the SEGRAM. The
DDRAM/CGRAM/SEGRAM is selected by the previous specification of the RM 1/0 bit. After a write, the
address is automatically incremented or decremented by 1 according to the I/D bit setting in the entry mode
set instruction. During the sleep and standby modes, the DDRAM, CGRAM, or SEGRAM cannot be
accessed.
RD7-0 :
Read 8-bit data from the DDRAM, CGRAM or SEGRAM. The DDRAM, CGRAM, or SEGRAM
is selected by the previous specification of the RM 1/0 bit. In the parallel bus interface mode, the first-byte
data read will be invalid immediately after the RAM address set, and the consecutive second-byte data will
be read normally. In the serial interface mode, two bytes will be invalid immediately after the start byte,
and the consecutive third-byte data will be read normally. For details, see the Serial Data Transfer section.
