Input/Output Ports (I/O)

MOTOROLA

16.6 Port D

Port D is an 7-bit special-function port that shares four of its pins with the

serial peripheral interface (SPI) module and three of its pins with two

timer interface (TIM1 and TIM2) modules. Port D also has software

configurable pullup devices if configured as an input port.

16.6.1 Port D Data Register

The port D data register (PTD) contains a data latch for each of the

seven port D pins.

PTD6–PTD0 — Port D Data Bits

These read/write bits are software-programmable. Data direction of

each port D pin is under the control of the corresponding bit in data

direction register D. Reset has no effect on port D data.

T2CH0 — Timer 2 Channel I/O Bits

The PTD6/T2CH0 pin is the TIM2 input capture/output compare pin.

The edge/level select bits, ELSxB:ELSxA, determine whether the

PTD6/T2CH0 pin is a timer channel I/O pin or a general-purpose I/O

pin. See Timer Interface Module (TIM).
