These bits are always read as 1.
Smart Card Data Transfer Direction
Selects the serial/parallel conversion format.
0: LSB-first in transfer
1: MSB-first in transfer
The bit setting is valid only when the transfer data
format is 8 bits. For 7-bit data, LSB-first is fixed.
Specifies inversion of the data logic level. The SINV 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
1: TDR contents are inverted before being transmitted.
Reserved
This bit is always read as 1.
This bit is set to 1 to make the SCI operate in smart
card interface mode.
0: Normal asynchronous mode or clocked synchronous
1: Smart card interface mode
data is stored as it is in RDR
Receive data is stored in inverted form in RDR
