Frequency Agile Transceiver
Data Sheet
The RX Config register is used to set options for receive mode operation.
Wake on Energy:
When enabled, the CDR circuit is held in reset until the energy threshold is met. This option can be used
to make the normal receiver function to perform similar to sniff. The energy dwell timer is used to determine how long the
receiver will stay on checking for energy (With FF in the energy dwell time register, the receiver will stay on until the threshold
is met).
Gate on Energy:
This option can be used in FM receive mode only, and will gate the data interface while the energy on RSSI
is below the energy threshold.
AM_FM_RX:
Sets the mode of operation for receive.
Force MICS Channel:
When this bit is set, the bits in Status2 used to show which channel the radio is on can be overwritten
to force a particular channel.

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-53000
will overwrite the contents of this register each time a new threshold is calculated.
