15.4.5
Only the internal clock generated by the on-chip baud rate generator can be used as the
communication clock in the smart card interface. The bit rate for the clock is set by the SCBRR
and the CKS1 and CKS0 bits in the SCSMR, and is calculated using the equation below. Table
15.4 shows sample bit rates. If clock output is then selected by setting CKE0 to 1, a clock with a
frequency 372 times the bit rate is output from the SCK0 pin.
Where: N

Note: The bit rate is rounded to two decimal places.
Calculate the value to be set in the bit rate register (SCBRR) from the operating frequency and the
bit rate. N is an integer in the range 0 N 255, specifying a smallish error.
