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.

Bit 3 Bit 2

BCP1 BCP0 Description

0 1 32 clock periods (Initial value)

0 64 clock periods

1 1 372 clock periods

0 256 clock periods

Bits 5, 4, 1, and 0: Operate in the same way as for the normal SCI. For details, see section 16.2.5,

Serial Mode Register (SMR).
