Table 12.3 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.

Unused bit.

SMR Setting: 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

12.3.5, Clock.

BRR Setting: BRR is used to set the bit rate. See section 12.3.5, Clock, for the method of

calculating the value to be set.

SCR Setting: The function of the TIE, RIE, TE, and RE bits is the same as for the normal SCI.

For details, see section 11, Serial Communication Interface.

Bit CKE0 specifies the clock output. Set these bits to 0 if a clock is not to be output, or to 1 if a

clock is to be output.
