Bit 6—Block Transfer Mode (BLK): Selects block transfer mode.
Bit 6
BLK
Description
0
Normal Smart Card interface mode operation
• Error signal transmission/detection and automatic data retransmission performed
• TXI interrupt generated by TEND flag
• TEND flag set 12.5 etu after start of transmission (11.0 etu in GSM mode)
1
Block transfer mode operation
• Error signal transmission/detection and automatic data retransmission not
performed
• TXI interrupt generated by TDRE flag
• TEND flag set 11.5 etu after start of transmission (11.0 etu in GSM mode)
Note: etu: Elementary time unit (time for transfer of 1 bit)
Bits 3 and 2—Basic Clock Pulse 1 and 2 (BCP1, BCP0): These bits specify the number of basic
clock periods in a 1-bit transfer interval on the Smart Card interface.
