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
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

Description
selects the input for pin MFOUT

modulation signal (envelope) from the internal encoder, Miller
pulse encoded
serial data stream to be transmitted, data stream before Miller
encoder
reserved
