TXPWR - Transmitter Output Power
Volatile Address = 0x4D; Non-Volatile Address = 0x02
The value in the TXPWR register sets the module's output power. Figure 35
shows the command and response and Figure 36 available power settings
and typical power outputs for the module. The default setting is 0x03.

ADDMODE - Addressing Mode
Volatile Address = 0x4F; Non-Volatile Address = 0x04
This register is controlled automatically by the HumPRC
the Join Process, so should not be changed by external commands.
DATATO - Transmit Wait Timeout
Volatile Address = 0x50; Non-Volatile Address = 0x05
This register selects options for transferring packet data in the HumPRO
Series. These options are controlled automatically by the HumPRC
application and do not have any effect on its operation.

UARTBAUD - UART Baud Rate
Volatile Address = 0x4E; Non-Volatile Address = 0x03
The value in UARTBAUD sets the data rate of the UART interface.
Changing the non-volatile register changes the data rate on the following
power-up or reset. Changing the volatile register changes the data rate
immediately following the command acknowledgement. Figure 37 shows
the command and response and Figure 38 shows the valid settings.

* These data rates are not supported by PC serial ports. Selection of these rates may
cause the module to fail to respond to a PC, requiring a reset to factory defaults.

If the module's UART baud rate is different than the host processor UART
baud rate then the module will not communicate correctly. If mismatched,
every rate can be tested until the correct one is found or the module can be
reset to factory defaults. The default baud rate is 9,600bps (0x01).
