o  STATE_C (STA3): 1- Initiate to Transmit; 0 - IDLE; 
 
State lines configuration 2:  
o  STATE_A (STA1): 1- Power on, and Calibration Completed; 0- Sleep; 
o  STATE_B (STA2): 1- Packets in Receiving Buffer; 0 – Receiving Buffer 
Free; 
o  STATE_C (STA3): 1- Packets full in Transmitting Buffer; 0 – Available in 
Transmitting Buffer; 
 
Performance Tips: the configuration 2 of state-lines can be used for the timing of read/write packets from 
serial; the configuration 1 can be used for prototyping and monitoring the behaviors of the radio with 
LEDs. 
 
ADDRESS (1 bit):  
1 – The module will backup the current address when setting up a new address; the 
old address will still be valid only in receiving packets destined to it. 
0 – The module will not backup the current address when setting up a new address. 
 
 
Default Configuration on Reset: 0. 
 
BACKOFF (1 bit): 
1 – The module will use a larger back-off window to avoid collision. (Set in dense 
networks with high traffic volume) 
0 – The module will use a smaller back-off window to improve throughput.  
 
Default Configuration on Reset: 0. 
 
Performance Tips: if there are more than two traffic flows with high bandwidth requirement, it is 
recommended to use the larger window (set BACKOFF=1); otherwise using BACKOFF=0 can provide 
slightly better performance. 
 
CHANNEL (2 bits): 
00 – Three channel operation; 
01 – Single channel operation on Channel 1; 
10 – Single channel operation on Channel 2;
