GRAPHICAL DATA WRITES
The busy state can be monitored on D7 when reading the DDRAM
address (RS line low). The busy state can also be monitored directly
from CN1/CN2 pin 3 if link J6 is set to 2&3.
PARALLEL COMMUNICATIONS
This module has a fast latching 8-bit data bus. The ‘RS’ and ‘R/W’
control lines should be set prior to the rising edge of the ‘E’ enable line.
Data is clocked in on the falling edge of the enable line. The busy line
should be checked before sending data.

The data bus width can be selected for 4-bit operation, using data lines
D4-D7. Within this mode, two writes are required to send one data byte.
The high nibble (bits 4-7) should be sent first, followed by the low nibble
(bits 0-3). The busy state is not triggered between nibbles. It is
important that the status is NOT read within 40us of sending the
command to set either 4 or 8 bit mode.
