RSSI output during RX (this value can be overwritten by a test function if the test
registers are unlocked)
Sniff cycle performed at multiple pre-defined channels
No operation defined
Linear mode
High gain mode
Normal gain mode
Force receive mode on a specific channel of the 9 defined channels
(status/Flag2)
AM receive mode
FM receive mode
Clock and data outputs gated for RSSI<energy threshold
Clock and data disabled until energy threshold met
6.5.1.2. Energy Threshold
Energy threshold sets the threshold for either wake on energy or sniff mode. If the automatic noise floor detection is enabled in sniff,
the AMIS-53050 will overwrite the contents of this register each time a new threshold is calculated.
