General Description
Pin Functions
1.6.9 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
Section 16. Input/Output (I/O) Ports.
1.6.10 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 Section 22. Timer
Interface Module (TIM), Section 20. Serial Peripheral Interface
Module (SPI), and Section 16. Input/Output (I/O) Ports.
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 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 Section 18. Enhanced Serial
Communications Interface (ESCI) Module and Section 16.
Input/Output (I/O) Ports.
PTE3 and PTE4 can also be programmed to be clock or oscillator pins.
See Section 8. Configuration Register (CONFIG) 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
MC68HC908GT16 • MC68HC908GT8 do not require termination,
termination is recommended to reduce the possibility of static damage.
