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

⚫ When enabled, the module receives wireless data
and it will follow an RSSI strength byte after output
via the serial port TXD
.---------------------------------------
⚫ In fixed point transmission, 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.

⚫ Valid only for mode 1.
1. In the receiving mode of WOR, the module can modify
the delay time after wake-up, the default time is 0;
2. The receiving end needs to send the command C0 09 02
03 E8 in the configuration mode (C0 is the write
command, 09 is the register starting address, 02 is the
length, 03 E8 is the set delay, the maximum FFFF is
65535ms, set to 0 turns 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).

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.
