Notes

1. Setting the pwon flag or the wake-up flag will clear the UVNOM flag.

2. The transceiver directly enters sleep mode and pin INH is set floating when the UVNOM flag is set (so after the

undervoltage detection time on either VCC or VI/O has elapsed before that voltage level has recovered).

3. When go-to-sleep command mode is selected for longer than the minimum hold time of the go-to-sleep command,

the transceiver will enter sleep mode and pin INH is set floating.

4. On entering normal mode the pwon flag and the wake-up flag will be cleared.
