30.4.4
Only the internal clock generated by the on-chip baud rate generator can be used as the
transmit/receive clock in the smart card interface. The bit rate is set using the bit rate register
(SCBRR) and the sampling register (SCSMPL), using the formula indicated below. Examples of
bit rates are listed in table 30.3
Here, when the CKE0 bit is set to 1 and the clock output is selected, a clock signal is output from
the SIM_CLK pin with frequency equal to (SCSMPL + 1) times the bit rate.
Table 30.3 Example of Bit Rates (bits/s) for SCBRR Settings
Note: The bit rate is a value that is rounded off below the decimal point.
