Description
Set to logic 1, the CRC co-processor calculates the CRC with MSB
first and the CRCResultMSB and the CRCResultLSB in the
CRCResultReg register are bit reversed.
Remark: During RF communication this bit is ignored.
Reserved for future use.
Set to logic 1 the transmitter can only be started, if an RF field is
generated.
Reserved for future use.
PolMFin defines the polarity of the MFIN pin. Set to logic 1, the polarity
of MFIN pin is active high. Set to logic 0 the polarity of MFIN pin is
active low.
Remark: The internal envelope signal is coded active low.
Reserved for future use.
Defines the preset value for the CRC co-processor for the command
CalCRC.
Remark: During any communication, the preset values is selected
