Smart Card Interface Mode (When SMIF in SCMR is 1)
Bit Bit Name Initial Value R/W Description
7 GM 0 R/W GSM Mode
Setting this bit to 1 allows GSM mode operation. In GSM
mode, the TEND set timing is put forward to 11.0 etu
from the start and the clock output control function is
appended. For details, see section 13.7.9, Clock Output
Control.
0: Normal smart card interface mode operation
(initial value)
(1) The TEND flag is generated 12.5 etu (11.5 etu in the
block transfer mode) after the beginning of the start
bit.
(2) Clock output on/off control only.
1: GSM mode operation in smart card interface mode
(1) The TEND flag is generated 11.0 etu after the
beginning of the start bit.
(2) In addition to clock output on/off control, high/how
fixed control is supported (set using SCR).
6 BLK 0 R/W Setting this bit to 1 allows block transfer mode operation.
For details, see section 13.7.4, Block Transfer Mode.
0: Normal smart card interface mode operation
(initial value)
(1) Error signal transmission, detection, and automatic
data retransmission are performed.
(2) The TXI interrupt is generated by the TEND flag.
(3) The TEND flag is set 12.5 etu (11.0 etu in the GSM
mode) after transmission starts.
1: Operation in block transfer mode
(1) Error signal transmission, detection, and automatic
data retransmission are not performed.
(2) The TXI interrupt is generated by the TDRE flag.
(3) The TEND flag is set 11.5 etu (11.0 etu in the GSM
mode) after transmission starts.
