selects the input for pin MFOUT

Description
selects the input of the contactless UART
after data transmission the activation of the receiver is delayed
for RxWait bit-clocks, during this ‘frame guard time’ any signal on
pin RX is ignored
this parameter is ignored by the Receive command
all other commands, such as Transceive, MFAuthent use this
parameter
the counter starts immediately after the external RF field is
switched on

reserved
constant LOW
Manchester with subcarrier from pin MFIN
modulated signal from the internal analog module, default
NRZ coding without subcarrier from pin MFIN which is only
valid for transfer speeds above 106 kBd
