address set DDRAM address to the
(lower bits) address counter.
-------------------------------------------------------------------------------------------------
Write data WD 0 1 Write data Writes data to DDRAM, 10
to RAM CGRAM, SEGRAM, or
annunciator.
-------------------------------------------------------------------------------------------------
Read data RD 1 1 Read data Reads data from DDRAM, 10
from RAM CGRAM, or SEGRAM.
