Bit 2—Smart Card Data Invert (SINV): Specifies inversion of the data logic level. This
function is used in combination with the SDIR bit to communicate with inverse-convention
cards.*

parity transmission and parity checking is based on the number of high-level periods at
the serial data I/O pin, and not on the register value.
Description
Unmodified TDR contents are transmitted
Receive data is stored unmodified in RDR
Inverted TDR contents are transmitted
Receive data is inverted before storage in RDR
