• INVDATA: INverted Data
0: The data field transmitted on TXD line is the same as the one written in US_THR register or the content read in US_RHR
is the same as RXD line. Normal mode of operation.
1: The data field transmitted on TXD line is inverted (voltage polarity only) compared to the value written on US_THR regis-
ter or the content read in US_RHR is inverted compared to what is received on RXD line (or ISO7816 IO line). Inverted
Mode of operation, useful for contactless card application. To be used with configuration bit MSBF.
• VAR_SYNC: Variable Synchronization of Command/Data Sync Start Frame Delimiter
0: User defined configuration of command or data sync field depending on MODSYNC value.
1: The sync field is updated when a character is written into US_THR register.
• MAX_ITERATION
Defines the maximum number of iterations in mode ISO7816, protocol T= 0.
• FILTER: Infrared Receive Line Filter
0: The USART does not filter the receive line.
1: The USART filters the receive line using a three-sample filter (1/16-bit clock) (2 over 3 majority).
• MAN: Manchester Encoder/Decoder Enable
0: Manchester Encoder/Decoder are disabled.
1: Manchester Encoder/Decoder are enabled.
• MODSYNC: Manchester Synchronization Mode
0:The Manchester Start bit is a 0 to 1 transition
1: The Manchester Start bit is a 1 to 0 transition.
• ONEBIT: Start Frame Delimiter Selector
0: Start Frame delimiter is COMMAND or DATA SYNC.
1: Start Frame delimiter is One Bit.
