Section 18 Smart Card Interface
18.3.5
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 bit rate
register (SCBRR) and the CKS1 and CKS0 bits in the serial mode register (SCSMR), and is
calculated using the equation below. Table 18.5 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 = Value set in SCBRR (0 ≤ N ≤ 255)

In the inverse convention type, the logical 1 level is state A, the logical 0 level is state Z, and
communication is MSB first. The start character data is H'3F. The parity bit is even (from the
smart card standards), and thus 0, which corresponds to state Z.
Only data bits D7 to D0 are inverted by the SINV bit. To invert the parity bit, set the O/E bit in
SCSMR to odd parity mode. This applies to both transmission and reception.
