AGCSTS2 (AGC STATUS2 REGISTER, 0x2274) R/W.
This register stores the average energy level of the received RF signal at antenna. The stored
energy level is the average of the received signal energy which is measured for the time interval
defined in RXEAWS field. The indicated value at AGCSTS2 register is stored as a 2’s
complement integer in dBm.
AGCSTS3 (AGC STATUS3 REGISTER, 0x2275) R/W.
This register stores the average energy level of the received packet. AGCSTS2 register
indicates the average of received signal’s energy level for a defined time interval. AGCSTS3
register shows the energy level of the last received packet. The value in AGCSTS3 register is
retained until another packet is received.
AGCSTS1 (AGC STATUS1 REGISTER, 0x2273)
This registers is used to monitor and control the gain of the VGA in the RF block.

LNA Gain. Used to monitor the LNA gain set by AGC block. The LNA
gain with LG=’1’ is 25 dB higher than with LG=’0’. When the value of the
LGF field is ‘0’, the LG field sets the gain of the LNA.
Reserved
VGA Gain Lock-up. Sets the gain of the VGA as a fixed value recorded
in the VG field. When the VGF field is set to ‘0’, the VGA gain is set to
the value recorded in the VG field. Only when the VGF field is set to ‘1’,
can the VGA gain be adjusted by the AGC block.
VGA Gain. Used to monitor the VGA gain set by the AGC block. The
VGA consists of three stages and the gain of the VGA can be set from 0
to 63dB in 1 dB steps. When the value of the VGF field is ‘0’, the VG
field sets the gain of the VGA.
