Output Drive Strength Selection for Port D Bits — Each of these control bits selects between low and high
output drive for the associated PTD pin. For port D pins that are configured as inputs, these bits have no effect.
0 Low output drive strength selected for port D bit n.
1 High output drive strength selected for port D bit n.
Port D Interrupt Flag — PTDIF indicates when a port D interrupt is detected. Writes have no effect on PTDIF.
0 No port D interrupt detected.
1 Port D interrupt detected.
Port D Interrupt Acknowledge — Writing a 1 to PTDACK is part of the flag clearing mechanism. PTDACK
always reads as 0.
Port D Interrupt Enable — PTDIE determines whether a port D interrupt is requested.
0 Port D interrupt request not enabled.
1 Port D interrupt request enabled.
Port D Detection Mode — PTDMOD (along with the PTDES bits) controls the detection mode of the port D
interrupt pins.
0 Port D pins detect edges only.
1 Port D pins detect both edges and levels.
