Description

BLK

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.
