15.3.4
Table 15.3 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.

Notes: — : Unused bit.
SMR Settings: 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 built-in baud rate generator, and bits BCP1
and BCP0 select the number of base clock cycles during transfer of one bit. For details, see section
15.3.5, Clock.
The BLK bit is cleared to 0 when using the normal smart card interface mode, and set to 1 when
using block transfer mode.
BRR Setting: BRR is used to set the bit rate. See section 15.3.5, Clock, for the method of
calculating the value to be set.
SCR Settings: The function of the TIE, RIE, TE, and RE bits is the same as for the normal SCI.
For details, see section 14, 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.
