Description
Reserved
These bits are always read as 1 and cannot be
modified.
Smart Card Data Transfer Direction
Selects the serial/parallel conversion format.
0: TDR contents are transmitted with LSB-first.
Stores receive data as LSB first in RDR.
1: TDR contents are transmitted with MSB-first.
Stores receive data as MSB first in RDR.
The SDIR 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.
Smart Card Data Invert
Specifies inversion of the data logic level. The SINV
bit does not affect the logic level of the parity bit.
When the parity bit is inverted, invert the O/E bit in
SMR.
0: TDR contents are transmitted as they are.
1: TDR contents are inverted before being
Reserved
This bit is always read as 1 and cannot be modified.
Smart Card Interface Mode Select
When this bit is set to 1, smart card interface mode
is selected.
0: Normal asynchronous or clock synchronous
1: Smart card interface mode

Receive data is stored as it is in RDR.
transmitted. Receive data is stored in inverted
form in RDR.
