IC (DIO Change Detect)
This command applies to the XBee 3 802.15.4 RF Module.
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 - P5). If the device detects a change on an enabled digital I/O pin, it immediately transmits a digital I/O sample to the address specified by DH + DL. If sleep is enabled, the edge transition must occur during a wake period to trigger a change detect.
The data transmission contains only DIO data.
IC is a bitmask you can use to enable or disable edge detection on individual digital I/O lines. Only DIO0 through DIO15 can be sampled using a Change Detect.
