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