Bit 6—Block Transfer Mode (BLK): Selects block transfer mode.
Bit 6
BLK Description
0 Normal smart card interface mode operation (Initial value)
• 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—Base Clock Pulse 1 and 2 (BCP1, BCP0): These bits specify the number of base
clock periods in a 1-bit transfer interval on the smart card interface.
Bit 3
BCP1
Bit 2
BCP0 Description
0 0 32 clock periods (Initial value)
1 64 clock periods
1 0 372 clock periods
1 256 clock periods
Bits 5, 4, 1, and 0—Operate in the same way as for the normal SCI. For details, see section
12.2.5, Serial Mode Register (SMR).
