IC (DIO Change Detect)
Set or read the digital I/O pins to monitor for changes in the I/O state.
IC works with the individual pin configuration commands (D0 - D9, P0 - P2). If you enable a pin as a
digital I/O, use the IC command to force an immediate I/O sample transmission when the DIO state
changes. If sleep is enabled, the edge transition must occur during a wake period to trigger a change
detect.
IC is a bitmask you can use to enable or disable edge detection on individual digital I/O lines. Only
DIO0 through DIO12 can be sampled using a Change Detect.
Set unused bits to 0.

Default
0
IF (Sleep Sample Rate)
Set or read the number of sleep cycles that must elapse between periodic I/O samples. This allows
the firmware to take I/O samples only during some wake cycles. During those cycles, the firmware
takes I/O samples at the rate specified by IR.
Parameter range
1 - 0xFF
