RegMACAddr0..25 - this bank holds the MAC addresses of all radios registered to a base or router. Up to
126 MAC addresses can be registered. Each bank parameter can hold up to five MAC addresses, with
each MAC address containing three bytes are in little-Endian order. Three-byte segments in a parameter
not holding a MAC address with hold a null address: 0x00 0x00 0x00. Note that unlike parameters in
other banks, the bank offset used in get commands is by parameter rather than by byte. Only one Bank 9
parameter can be retrieved at a time with a get command. In a remote, this bank will contain only null
addresses.

UcReset - writing a value of 0x00 to this location forces a software reset of the microcontroller. This will
enable those changes which require a reset. If this is written to before 0x01 is written to the MemorySave
parameter, the last parameter values saved before the reset will be in effect. A reply packet, either local
or over-the-air, may not be received when writing a value to this register. Writing 0x5A to this location will
reset the radio and load the factory default settings. This is equivalent to writing 0x00 to UcReset followed
by writing 0x00 to MemorySave. Note that 0x01 must be written to MemorySave to save the retrieved
factory defaults.

SleepModeOverride - when remotes are operating in sleep mode, writing 0x01 to the location will cause
the remotes to stay awake. Writing 0x00 to this location causes the remotes to resume sleeping in
10 seconds. Writing 0x02 to this location causes the remotes to resume sleeping immediately (subject to
their configuration).

RoutingTableUpd - this parameter is the interval in seconds for the base station to broadcast the tree-
routing table to its system. The default interval is 20 seconds.

DiagSerialRate - sets the diagnostic port serial rate divisor according to the following formula:
Serial rate in b/s = 460800/DiagSerialRate
