PRSSI - Last Good Packet RSSI
Volatile Address = 0x7B
This register holds the received signal strength in dBm of the last
successfully received packet. A successful packet reception is one that
causes payload data to be output on the UART interface. The value in this
register is overwritten each time a new packet is successfully processed.
The register value is an 8-bit signed integer representing the RSSI in dBm.
It is accurate to ±3dB.

ARSSI - Ambient RSSI
Volatile Address = 0x7C
This register returns the ambient receive signal strength on the current
channel in dBm. The signal strength is measured as soon as the command
is received. The register value is an 8-bit signed integer representing the
RSSI in dBm. It is accurate to ±3dB at the high RF data rate, and +3 to
-20 dB at the low RF data rate. The channel being read may be any of the
channels in the selected hopping sequence.

FWVER - Firmware Version
Non-Volatile Address = 0xC0 - 0xC3
These read-only registers contain the firmware version number currently
on the module. Each byte is a hexadecimal value: 12 03 01 00 indicates
version 18.3.1.0. Each register byte is read separately. Figure 65 shows the
Firmware Version registers.
