Table 11-8.
Table 11-8 shows the LCD data pins and GPIO pins used for each mode of operation and the
ordering of pixels delivered to a screen for each mode of operation. Figure 11-8 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 Section 9, “System Control
Module” on page 9-1 for configuration information. Also note that SDS is ignored in active mode
(PAS=1).
