Section 14 Serial Communication Interface (SCI)
Bit 3—Smart Card Data Transfer Direction (SDIR): Selects the serial/parallel conversion
format.
This bit is valid when 8-bit data is used as the transmit/receive format.
Bit 3
SDIR
0
1
Bit 2—Smart Card Data Invert (SINV): Specifies inversion of the data logic level. The SINV
bit does not affect the logic level of the parity bit(s): parity bit inversion requires inversion of the
O/E bit in SMR.
Bit 2
SINV
0
1
Bit 1—Reserved: This bit cannot be modified and is always read as 1.
Bit 0—Smart Card Interface Mode Select (SMIF): When the smart card interface operates as a
normal SCI, 0 should be written to this bit.
