Write Data to RAM
WD7-0 :
Write 8-bit data to the DDRAM and CGRAM. The DDRAM or CGRAM is selected by the
previous specification of the RM bit. After a write, the address is automatically incremented or
decremented by 1 according to the I/D bit setting. During the sleep and standby modes, the DDRAM or
CGRAM cannot be accessed.
