Change RF Channel Procedure
The RF Transceiver operates in 2.4GHz ISM band. The operating frequency is divided into 16 channels. The proce-
dure to change the channels is described as below.

Set the RF channel. Users can select one of the channels by configuring either LREG0x200 or LREG0x254.
Turn on the TX MAC gated clock by setting SREG0x26 [2] to 1. To avoid an incomplete acknowledgment frame
transmission happen during RF state machine reset period.
Reset RF Transceiver state machine by setting SREG0x36 [2] to 1 and then set SREG0x36 [2] back to 0.
After RF Transceiver reset, delay for a while to ensure the acknowledgment frame, if any, is successfully transmitted.
250 kbps mode: delay 550 s
1M bps mode: delay 300 s
To disable the TX MAC gated clock by setting SREG26 [2] to 0.
