Table 17.3 shows a bit map of the registers used by the smart card interface. Bits indicated as 0 or
1 must be set to the value shown. The setting of other bits is described below.

Note: A dash indicates an unused bit.
Serial Mode Register (SCSMR1) Settings: The GM bit is used to select the timing of TEND flag
setting, and, together with the CKE1 and CKE0 bits in the serial control register (SCSCR1), to
select the clock output state.
The O/E bit is cleared to 0 if the IC card is of the direct convention type, and set to 1 if of the
inverse convention type.
Bits CKS1 and CKS0 select the clock source of the on-chip baud rate generator. See section
17.3.5, Clock.
If a parity error occurs, however, the receiving station outputs an error signal (DE, low-level)
to request retransmission of the data. After outputting the error signal for the prescribed length
of time, the receiving station places the signal line in the high-impedance state again. The
signal line is pulled high again by a pull-up resistor.
frame.
If it receives an error signal, however, it returns to step 2 and retransmits the erroneous data.
