General Description
1.5.7 Port A Input/Output (I/O) Pins (PTA7/KBD7–PTA0/KBD0)
PTA7–PTA0 are general-purpose, bidirectional I/O port pins. Any or all of the port A pins can be
programmed to serve as keyboard interrupt pins. See
Chapter 9 Keyboard Interrupt Module
These port pins also have selectable pullups when configured for input mode. The pullups are disengaged
when configured for output mode. The pullups are selectable on an individual port bit basis.
1.5.8 Port B I/O Pins (PTB7/AD7–PTB0/AD0)
PTB7–PTB0 are general-purpose, bidirectional I/O port pins that can also be used for analog-to-digital
converter (ADC) inputs. See
Analog-to-Digital Converter
1.5.9 Port C I/O Pins (PTC6–PTC0)
PTC6–PTC0 are general-purpose, bidirectional I/O port pins. PTC0–PTC4 have higher current
sink/source capability. PTC5 and PTC6 are only available on the 44-pin QFP package.
These port pins also have selectable pullups when configured for input mode. The pullups are disengaged
when configured for output mode. The pullups are selectable on an individual port bit basis. See
Chapter 12 Input/Output (I/O) Ports
1.5.10 Port D I/O Pins (PTD7/T2CH1–PTD0/SS)
PTD7–PTD0 are special-function, bidirectional I/O port pins. PTD0–PTD3 can be programmed to be
serial peripheral interface (SPI) pins, while PTD4–PTD7 can be individually programmed to be timer
interface module (TIM1 and TIM2) pins. See
Peripheral Interface (SPI)
These port pins also have selectable pullups when configured for input mode. The pullups are disengaged
when configured for output mode. The pullups are selectable on an individual port bit basis.
1.5.11 Port E I/O Pins (PTE4–PTE2, PTE1/RxD, and PTE0/TxD)
PTE0–PTE4 are general-purpose, bidirectional I/O port pins. PTE0–PTE1 can also be programmed to be
serial communications interface (SCI) pins. See
(ESCI) Module
PTE3 and PTE4 can also be programmed to be clock or oscillator pins. See
Register (CONFIG)
