1：Fixed point transmission mode
0 ： Transparent transmission mode
（default）
---------------------------------------
5 Enable repeater
1：Enable repeater function
0：Disable repeater function(default)
--------------------------------------
4 LBT enable (monitor before
transmission)
1：Enable
0：Disable（default）
--------------------------------------
3 WOR transceiver control
1：WOR transmitter
The module receiving and
transmitting functions are turned on, and a
wake-up code is added when transmitting data.
Receiving is turned on.
0：WOR receiver（default）
The module is unable to transmit data
and works in WOR monitoring mode. The
monitoring period is as follows (WOR cycle),
which can save a lot of power.
---------------------------------------
2，1，0，WOR cycle
000：500ms
001：1000ms
010：1500ms
011：2000ms
100：2500ms
101：3000ms
110：3500ms
111：4000ms
---------------------------------------
 After the reply function is enabled, if the target
address is not the module itself, the module will
forward it once.

In order to prevent data return-back, it is
recommended to use it in conjunction with the fixed
point mode. That is: the target address is different
from the source address.
----------------------------------------
 When enabled, wireless data will be monitored
before it is transmitted, which can avoid interference
to a certain extent, but may cause data delay.
----------------------------------------
 Valid only for mode 1.
 After the WOR receiver receives the wireless data
and outputs it through the serial port, it will wait for
1000ms before entering the WOR again. Users can
input the serial port data and return it via the wireless
during this period. Each serial byte will be refreshed
for 1000ms. Users must transmit the first byte within
1000ms.
---------------------------------------------
 Valid only for mode 1.

Period T = (1 + WOR) * 500ms, maximum 4000ms,
minimum 500ms
 The longer the WOR monitoring interval period, the
lower the average power consumption, but the
greater the data delay
 Both the transmitter and the receiver must be the
same (very important).
07H
Write
CRYPT_
H
Key high byte (default 0）

Write only, read returns 0

Used for user encryption to avoid intercepting
airborne wireless data by similar modules.

The module will internally use these two bytes as a
calculation factor to transform and encrypt the
over-the-air wireless signal.

L
Key low byte (default 0)
