‘3h’, or with 48 MHz CPU clock and <SSCBR> set to ‘2h’. When 40 MHz CPU clock is used the maximum
baud rate cannot be higher than 6.6Mbaud (<SSCBR> = ‘2h’) due to the limited granularity of <SSCBR>.
Value ‘1h’ for <SSCBR> may be used only with CPU clock equal to (or lower than) 32 MHz (after checking
that timings are in line with the target slave).
t
Where <SSCBR> represents the content of the SSC baud rate register, taken as unsigned 16-bit integer.
