General Description
Decoupling of these pins should be as per the digital supply. See
(ADC).
V
reference supply for the ADC, and is internally connected to V
1.5.8 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
10 Keyboard Interrupt (KBI)
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.
1.5.9 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
Converter
1.5.10 Port C I/O Pins (PTC6–PTC0)
PTC6–PTC0 are general-purpose, bidirectional I/O port pins. See
PTC5 and PTC6 are only available on 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.
1.5.11 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 Module
available on 42-SDIP and 44-pin QFP packages.
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.
1.5.12 Port E I/O Pins (PTE1/RxD–PTE0/TxD)
PTE0–PTE1 are general-purpose, bidirectional I/O port pins. These pins can also be programmed to be
serial communications interface (SCI) pins. See
