Section 14 Smart Card Interface
Bit 6—Block Transfer Mode (BLK): Selects block transfer mode.
Note: etu : Elementury time unit (time for transfer of 1 bit)
Bits 3 and 2—Basic Clock Pulse 1 and 0 (BCP1, BCP0): These bits specify the number of basic
clock periods in a 1-bit transfer interval on the Smart Card interface.
Bits 5, 4, 1, and 0: Operate in the same way as for the normal SCI. For details, see section 13.2.5,
