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
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.

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.

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;
