Description
CRC coprocessor calculates the CRC with MSB first. In the
CRCResultReg register the values for the CRCResultMSB[7:0]
bits and the CRCResultLSB[7:0] bits are bit reversed
Remark:
during RF communication this bit is ignored
reserved for future use
transmitter can only be started if an RF field is generated
reserved for future use
defines the polarity of pin MFIN
Remark:
the internal envelope signal is encoded active LOW,
changing this bit generates a MFinActIRq event
polarity of pin MFIN is active HIGH
polarity of pin MFIN is active LOW
reserved for future use
defines the preset value for the CRC coprocessor for the CalcCRC
command
Remark:
during any communication, the preset values are
selected automatically according to the definition of bits in the
RxModeReg and TxModeReg registers
