General Description
1.5.10 Port C I/O Pins (PTC6–PTC0/CANTX)
PTC6 and PTC5 are general-purpose, bidirectional I/O port pins. PTC4–PTC0 are
general-purpose, bidirectional I/O port pins that contain higher current sink/source
capability. PTC6–PTC2 are only available on the 48-pin LQFP package. See
Section 17. Input/Output (I/O) Ports.
PTC1 and PTC0 can be programmed to be MSCAN08 pins.
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. PTD3–PTD0 can be
programmed to be serial peripheral interface (SPI) pins, while PTD7–PTD4 can be
individually programmed to be timer interface module (TIM1 and TIM2) pins. PTD7
is only available on the 48-pin LQFP package. See Section 23. Timer Interface
Module (TIM), Section 21. Serial Peripheral Interface (SPI) Module, and
Section 17. 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.
1.5.12 Port E I/O Pins (PTE5–PTE2, PTE1/RxD, and PTE0/TxD)
PTE5–PTE0 are general-purpose, bidirectional I/O port pins. PTE1 and PTE0 can
also be programmed to be enhanced serial communications interface (ESCI) pins.
PTE5–PTE2 are only available on the 48-pin LQFP package. See Section 19.
Enhanced Serial Communications Interface (ESCI) Module and Section 17.
Input/Output (I/O) Ports.
NOTE:
Any unused inputs and I/O ports should be tied to an appropriate logic level (either
VDD or VSS). Although the I/O ports of the MC68HC908GZ8 do not require
termination, termination is recommended to reduce the possibility of static damage.
