Port D is an 8-bit special function port that shares two of its pins with the
serial communications interface module (see
pins with the timer 1 interface module, (see
pins with the analog-to-digital converter module (see
PTD6 and PTD7 each has high current sink (25mA) and programmable
pull-up. PTD2, PTD3, PTD6 and PTD7 each has LED sink capability.
PTD0–PTD1 are available on 28-pin and 32-pin packages only.
The port D data register contains a data latch for each of the eight port D
