Reserved

These bits are always read as 1.

SDIR

R/W

Smart Card Data Transfer Direction

Selects the serial/parallel conversion format.

0: Transfer with LSB-first

1: Transfer with MSB-first

This bit is valid only when the 8-bit data format is used for

transmission/reception; when the 7-bit data format is

used, data is always transmitted/received with LSB-first.

SINV

R/W

Smart Card Data Invert

Inverts the transmit/receive data logic level. This bit does

not affect the logic level of the parity bit. To invert the

parity bit, invert the O/

E bit in SMR.

0: TDR contents are transmitted as they are. Receive

data is stored as it is in RDR.

1: TDR contents are inverted before being transmitted.

Receive data is stored in inverted form in RDR.



Reserved

This bit is always read as 1.

SMIF

R/W

Smart Card Interface Mode Select

When this bit is set to 1, smart card interface mode is

selected.

0: Normal asynchronous or clocked synchronous mode

1: Smart card interface mode
