Peripheral Control Module

Table 11-8shows 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 11-8shows 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 9.1, “General-Purpose I/O” on page 9-1for configuration information. Also note that SDS is ignored in active mode (PAS=1).
