bit will remain set until cleared in software or the start of the External Interrupt 1
service routine. If IT1=0, this bit will inversely reflect the state of the INT1B pin.
0 = INT1B is level triggered (Level detect type).
1 = INT1B is edge triggered (Edge detect type).

This bit is set when an edge/level type defined by IT1 flag is detected. If IT1=1, this
This bit selects whether the INT1B pin will detect the edge/level triggered interrupts.
This bit is set when an edge/level type defined by IT0 flag is detected. If IT0=1, this
This bit selects whether the INT0B pin will detect the edge/level triggered interrupts.
