Electrical characteristics

48 MHz CPU clock and <SSCBR> set to ‘2h’. When 40 MHz CPU clock is used the maximum baudrate cannot be higher
than 6.6 Mbaud (<SSCBR> = ‘2h’) due to the limited granularity of <SSCBR>. Value ‘1h’ for <SSCBR> may be used only
with CPU clock lower than 32 MHz (after checking that resulting timings are suitable for the master).
Where <SSCBR> represents the content of the SSC Baudrate register, taken as unsigned 16-bit integer.
