Description
Reserved
Static AGC value used for reader mode
CLIF_AGC_CONFIG0_REG.AGC_INPUT_SEL = 1 &
CLIF_AGC_CONFIG0_REG.MODE_SEL = 0
Most sensitive: largest Rx-resistor, i.e., none of the
switchable resistors is added in parallel
Most robust: smallest Rx-resistor, i.e., all switchable
resistors are added in parallel
Reserved
Static AGC value used for card mode
CLIF_AGC_CONFIG0_REG.AGC_INPUT_SEL = 0 &
CLIF_AGC_CONFIG0_REG.MODE_SEL = 0.
Note: That in reset CLIF_AGC_CONFIG0_REG = 0x00 and
CLIF_AGC_INPUT_REG = 0x00 and therefore the AGC
output is AGC_CM_VALUE = 0x00.
Most sensitive: largest Rx-resistor, i.e., none of the
switchable resistors is added in parallel
Most robust: smallest Rx-resistor, i.e., all switchable
resistors are added in parallel
Description
Reserved
RSSI: Current value of the AGC
Most sensitive: largest Rx-resistor, i.e., none of the
switchable resistors are added in parallel
Most robust: smallest Rx-resistor, i.e., all switchable
resistors are added in parallel
RSSI: Q-channel ADC value (for RSSI DC coupling shall be
used)
