PORTD is not implemented on PIC16F1933/1936/1938 devices, read as ‘0’.
TRISD is not implemented on PIC16F1933/1936/1938 devices, read as ‘0’.
PORTD implemented on PIC16F1934/1937/1939/PIC16LF1934/1937/1939 devices only.
Writes to PORTD are actually written to corresponding LATD register. Reads from PORTD register is
return of actual I/O pin values.
