Port B Interrupt Pin Selects — Each of the PTBPSn bits enable the corresponding port B interrupt pin.
0 Pin not enabled as interrupt.
1 Pin enabled as interrupt.
Port B Edge Selects — Each of the PTBESn bits serves a dual purpose by selecting the polarity of the active
interrupt edge as well as selecting a pull-up or pull-down device if enabled.
0 A pull-up device is connected to the associated pin and detects falling edge/low level for interrupt generation.
1 A pull-down device is connected to the associated pin and detects rising edge/high level for interrupt
