PORTD is an 8-bit port with Schmitt Trigger input
buffers. Each pin is individually configurable as an input
or output.
PORTD can be configured as an 8-bit wide
microprocessor port (Parallel Slave Port) by setting
control bit, PSPMODE (TRISE<4>). In this mode, the
input buffers are TTL.

Input buffers are Schmitt Triggers when in I/O mode and TTL buffers when in Parallel Slave Port mode.
PORTD and TRISD are not implemented
on the 28-pin devices.
