Description
R/W
When this bit is set to 1, the SCI operates in block
transfer mode. For details on block transfer mode,
refer to section 15.7.3, Block Transfer Mode.
0: Normal smart card interface mode operation
(initial value)
• Error signal transmission, detection, and
automatic data retransmission are performed.
• The TXI interrupt is generated by the TEND
flag.
• The TEND flag is set 12.5 etu (11.0 etu in the
GSM mode) after transmission starts.
1: Operation in block transfer mode
• Error signal transmission, detection, and
automatic data retransmission are not
performed.
• The TXI interrupt is generated by the TDRE
flag.
• The TEND flag is set 11.5 etu (11.0 etu in the
GSM mode) after transmission starts.
R/W
Parity Enable (enabled only in asynchronous
mode)
When this bit is set to 1, the parity bit is added to
transmit data in transmission, and the parity bit is
checked in reception. In Smart Card interface
mode, this bit must be set to 1.
R/W
Parity Mode (enabled only when the PE bit is 1 in
asynchronous mode)
0: Selects even parity.
1: Selects odd parity.
For details on setting this bit in Smart Card
interface mode, refer to section 15.7.2, Data
Format (Except for Block Transfer Mode).
