$17: Interrupt Latch Reset (Read/Write)
CLR_INT1
CLR_INT2
00: INT1 Register is detecting Level while INT2 is detecting Pulse.
01: INT1 Register is detecting Pulse while INT2 is detecting Level.
10: INT1 Register is detecting a Single Pulse and INT2 is detecting Single Pulse (if 2
time window and second time window > 0 then INT2 will detect the double pulse only.
INTPIN: INT1 pin is routed to INT1 bit in Detection Source Register ($0A) and INT2 pin is routed to INT2 bit in Detection Source
Register ($0A).
INTPIN: INT2 pin is routed to INT1 bit in Detection Source Register ($0A) and INT1 pin is routed to INT2 bit in Detection Source
Register ($0A).
