BANK
BANK: Controls how the registers are addressed (see
1 = The registers associated with each port are separated into different banks
0 = The registers are in the same bank (addresses are sequential)
MIRROR: INT pins mirror bit
1 = The INT pins are internally connected in a wired OR configuration
0 = The INT pins are not connected. INTA is associated with Port A and INTB is associated with Port B
SEQOP: Sequential Operation mode bit.
1 = Sequential operation disabled, address pointer does not increment.
0 = Sequential operation enabled, address pointer increments.
Unimplemented: Reads as 0
Unimplemented: Reads as 0
ODR: Configures the INT pin as an open-drain output.
1 = Open-drain output (overrides the INTPOL bit).
0 = Active driver output (INTPOL bit sets the polarity).
INTPOL: Sets the polarity of the INT output pin.
1 = Active-high.
0 = Active-low.
INTCC: Interrupt Clearing Control
1 = Reading INTCAP register clears the interrupt
0 = Reading GPIO register clears the interrupt
