Note:
SMR Setting
The GM bit is cleared to 0 in normal smart card interface mode, and set to 1 in GSM mode. 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
13.3.5, Clock.
BRR Setting
BRR is used to set the bit rate. See section 13.3.5, 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 12, Serial Communication Interface (SCI).
Bits CKE1 and CKE0 specify the clock output. When the GM bit in SMR is cleared to 0, set these
bits to B'00 if a clock is not to be output, or to B'01 if a clock is to be output. When the GM bit in
SMR is set to 1, clock output is performed. The clock output can also be fixed high or low.
