WOR transceiver control

：
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.

When enabled, the module receives wireless data and
it will follow an RSSI strength byte after output via
the serial port TXD
.---------------------------------------
The module recognizes the first three bytes of the
serial data as: address high + address low + channel
and takes it as the wireless transmitting target.
---------------------------------------
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 for mode 1 only
：
1. In the receiving mode of WOR, the module can
modify the delay time after wake-up, and the default
time is 0;
2. The receiving end needs to send the instruction C0
09 02 03 E8 in configuration mode (C0 is the write
command, 09 is the register starter address, 02 is the
length, 03 E8 is the set delay, the maximum FFFF is
65535ms, set to 0 to turn off the wake-up delay. )
3. Data can be sent within the delay
---------------------------------------------
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).

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.
