Inversion specified by the SINV bit applies only to the data bits, D7 to D0. For parity bit
inversion, the O/E bit in SCSMR1 is set to odd parity mode. (This applies to both transmission and
reception).
17.3.5
Only an internal clock generated by the on-chip baud rate generator can be used as the
transmit/receive clock for the smart card interface. The bit rate is set with the bit rate register
(SCBRR1) and the CKS1 and CKS0 bits in the serial mode register (SCSMR1). The equation for
calculating the bit rate is shown below. Table 17.5 shows some sample bit rates.
If clock output is selected with CKE0 set to 1, a clock with a frequency of 372 times the bit rate is
output from the SCK pin.
Where: N = Value set in SCBRR1 (0 ≤ N ≤ 255)
