the associated pin.
The following tables break out pin options on a peripheral by peripheral basis.
1. There is one special case with regard to pullup enable functions. PTA0 can be programmed to operate as IRQ. When in that
mode, the pullup enable is controlled via IRQSC[IRQPDD].

These pins that are shared with the LCD are open-drain by default if not used as LCD pins. To configure this pins as full
complementary drive outputs, you must have the LCD modules bits configured as follow: FCDEN =1, VSUPPLY = 11 and RVEN
= 0. The Input levels and internal pullup resistors are referenced to VLL3. Referer to the LCD chapter for further information.
