Freescale Semiconductor, Inc.
General Description
1.6.10 Port C I/O Pins (PTC6—PTC0)
PTC6–PTC0 are general-purpose, bidirectional I/O port pins. See
Section 16. Input/Output (I/O) Ports. 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.
1.6.11 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 Section 22. Timer
Interface Module (TIM), Section 20. Serial Peripheral Interface
Module (SPI), and Section 16. Input/Output (I/O) Ports. PTD6 and
PTD7 are only 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.
1.6.12 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 Section 18. Serial Communications Interface Module (SCI)
and Section 16. Input/Output (I/O) Ports.
NOTE:
Any unused inputs and I/O ports should be tied to an appropriate logic
level (either V_DD or V_SS). Although the I/O ports of the
MC68HC908GP32 do not require termination, termination is
recommended to reduce the possibility of static damage.
