shows the LCD
data pin pixel ordering. Note that when dual-panel color operation is enabled, the user must
configure GPIO pins 2 through 9 as outputs by setting bits 2..9 within the GPIO pin direction
register (GPDR) and GPIO alternate function register (GAFR). See the
“General-Purpose I/O” on page 9-1
for configuration information. Also note that SDS is ignored in
active mode (PAS=1).
