13. Serial Communication Interface (SCI)
13.7.4
In smart card interface mode an internal clock generated by the on-chip baud rate generator can
only be used as a transmit/receive clock. In this mode, the SCI operates on a basic clock with a
frequency of 32, 64, 372, or 256 times the bit rate (fixed to 16 times in normal asynchronous
mode) as determined by bits BCP1 and BCP0. In reception, the SCI samples the falling edge of
the start bit using the basic clock, and performs internal synchronization. As shown in figure
13.25, by sampling receive data at the rising edge of the 16th, 32nd, 186th, or 128th pulse of the
basic clock, data can be latched at the middle of the bit. The reception margin is given by the
following formula.
Where M: Reception margin (%)
Assuming values of F = 0, D = 0.5, and N = 372 in the above formula, the reception margin
formula is as follows.
M = (0.5 – 1/2 × 372) × 100%
