Section 14 Smart Card Interface
14.3.5
As its serial communication clock, the smart card interface can use only the internal clock
generated by the on-chip baud rate generator. The bit rate can be selected by setting the bit rate
register (BRR) and bits CKS1 and CKS0 in the serial mode register (SMR). The bit rate can be
calculated from the equation given below. Table 14.5 lists some examples of bit rate settings.
If bit CKE0 is set to 1, a clock signal with a frequency equal to 372 times the bit rate is output
from the SCK
where, N: BRR setting (0
