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（default）
100：2500ms
101：3000ms
110：3500ms
111：4000ms
 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).

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.
