Interrupt Request Output on the SDO Pin.
nIRQ output is present on the SDO pin if this bit is set and the nSEL input is inactive (high).
Direct I/O for GPIO2.
If the GPIO2 is configured to be a direct output then the value on the GPIO pin can be set
here. If the GPIO2 is configured to be a direct input then the value of the pin can be read
here.
Direct I/O for GPIO1.
If the GPIO1 is configured to be a direct output then the value on the GPIO pin can be set
here. If the GPIO1 is configured to be a direct input then the value of the pin can be read
here.
Direct I/O for GPIO0.
If the GPIO0 is configured to be a direct output then the value on the GPIO pin can be set
here. If the GPIO0 is configured to be a direct input then the value of the pin can be read
here.
