R ea d D e st i n at i o n Ad d r es s
The OEM Host issues this command to the transceiver to read the
destination address.
Note: Only the three Least Significant Bytes of the MAC Address are
used for packet delivery.
F o r c ed C al i br at i o n
The OEM Host issues this command to force a recalibration to occur.
During the recalibration, the radio will assert CTS high. Recalibration
can take up to 3 seonds and the command response will not be sent to
the OEM Host until recalibration is complete.
A ut o D es t i na t i o n
The Host issues this command to change the Auto Destination & Auto
Channel
Destination/Auto Channel settings will only be changed if the
corresponding enable bit is set.
