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