General Description
1.5.6 Port A I/O Pins (PTA6/SS, PTA5/SPSCK, PTA4/KBD4–PTA0/KBD0)
Port A input/output (I/O) pins (PTA6/SS, PTA5/SPSCK, PTA4/KBD4, PTA3/KBD3, PTA2/KBD2,
PTA1/KBD1, and PTA0/KBD0) are special-function, bidirectional I/O port pins. PTA5 and PTA6 are
shared with the serial peripheral interface (SPI). PTA4-PTA0 can be programmed to serve as keyboard
interrupt pins.

1.5.7 Port B I/O Pins (PTB7/AD7/TBCH1, PTB6/AD6/TBCH0, PTB5/AD5–PTB0/AD0)
PTB7/AD7/TBCH1, PTB6/AD6/TBCH0, and PTB5/AD5–PTB0/AD0 are special-function, bidirectional I/O
port pins that can also be used for ADC inputs. PTB7/AD7/TBCH1 and PTB6/AD6/TBCH0 are special
function bidirectional I/O port pins that can also be used for timer interface pins.

1.5.8 Port C I/O Pins (PTC4/OSC1, PTC3/OSC2, PTC2/MCLK, PTC1/MOSI, PTC0/MISO)
PTC4/OSC1–PTC0/MISO are special-function, bidirectional I/O port pins. See

When applications require:
PTC2/MCLK is software selectable to be MCLK, or bus clock out. PTC1/MOSI can be programmed to be
the MOSI signal for the SPI. PTC0/MISO can be programmed to be the MISO signal for the SPI.
1.5.9 Port D I/O Pins (PTD1/TACH1–PTD0/TACH0)
PTD1/TACH1–PTD0/TACH0 are special-function, bidirectional I/O port pins that can also be programmed
to be timer pins.
See
1.5.10 Port E I/O Pins (PTE1/RxD–PTE0/TxD)
PTE1/RxD–PTE0/TxD are special-function, bidirectional I/O port pins that can also be programmed to be
enhanced serial communication interface (ESCI) pins.
