Port D is an 8-bit special-function port that shares four of its pins with the
serial peripheral interface (SPI) module and four 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.
The port D data register (PTD) contains a data latch for each of the eight
port D pins.
Bit 7 and bit 6 of PTD are not available in a 40-pin dual in-line
package.

Read:
Write:
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.
The PTD7/T2CH1–PTD6/T2CH0 pins are the TIM2 input
capture/output compare pins. The edge/level select bits,
ELSxB:ELSxA, determine whether the PTD7/T2CH1–PTD6/T2CH0
pins are timer channel I/O pins or general-purpose I/O pins.
