Notes - If t2 < 5 us, the RF68 will not turn into Tx mode during the recovery command (if not previously in Tx mode)

- If t1 < 5 us, with t0 > 5 us, the RF68 will not turn into Tx mode in the second scenario of recovery command

- During the Pulsed recovery command, t0 timing does not have any upper limit

- If t1 or t2 exceeds 5us, the recovery command will still be successful, but the transmitter will momentarily turn on
