Block transfer mode
0 Operation of normal smart card interface mode
(1) Error signal output, detection, and automatic resending of data;
(2) TXI interrupt generated by TEND flag;
(3) TEND flag set 12.5etu after start of transmission (after 11.0etu in GSM mode).
1 Operation in block transfer mode
(1) No error signal output, detection, or automatic resending of data;
(2) TXI interrupt generated by TDRE flag;
(3) TEND flag set 11.5etu after start of transmission (after 11.0etu in GSM mode).
GSM Mode
0 Operation in normal smart card interface mode
(1)TEND flag set 12.5etu (11.5etu in block transfer mode) after start of first bit;
(2)ON/OFF control only of clock output.
1 Operation in GSM mode smart card interface mode
(1)TEND flag set 11.0etu after start of first bit;
(2)In addition to ON/OFF control of clock output, High/Low control also enabled (set by SCR).
Note: etu: Elementary Time Unit. The time to send 1 bit.
Note: Set bit 5 to 1 when using the smart card interface.
