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