Register Description
18.2 Command Register
Figure 28
AFFC (Average Filter Frequency Control) enables direct control of the average filter cut-off frequency.
IFLA (IF Level Attenuation) controls the maximum gain of the IF amplifier in OOK modulation.
The reduction in gain can be observed if the IF amplifier AGC system is disabled (by setting RAGC = 1).
MODE selects the mode.
RSSIE (RSSI Enable) enables the RSSI function.
EDD (Envelop Detector Decay) controls the envelop detector decay.
RAGC (Reset Automatic Gain Control) resets both receiver internal AGCs.

Reset Value
Bit Name
Access
0 = Average filter cut-off frequency is defined by DR[1:0]
1 = Average filter cut-off frequency is defined by AFF[1:0]
0 = No effect
1 = Decreases by 20 dB (typical) the maximum gain of the IF amplifier, in OOK modulation only
0 = Receive mode
1 = Transmit mode
0 = Disabled
1 = Enabled
0 = Slow decay for minimum ripple
1 = Fast decay
0 = No action
