Note:
RECEIVER FREQUENCY HOP
OPTIMIZED CYCLE
MRF89XA is in RX mode
On channel 1 (R1/P1/S1)
It is also possible to move from one channel to another without having to switch off the receiver. This method
is faster and overall draws more current. For timing information, refer to TSRHOP.

1. Set R2/P2/S2
2. Set MRF89XA in FS mode, change
Frequency Band Select bits (FBS<1:0>), then switch
from R1/P1/S1 to R2/P2/S2
MRF89XA is now ready
for data reception
Set MRF89XA back in RX mode
