Max. baud rate

6.6 MBd(1)

@FCPU = 40 MHz

(<SSCBR> = 0002h)

Maximum baud rate is in reality 8Mbaud, that can be reached with 64 MHz CPU clock and <SSCBR> set to

‘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 lower than 32 MHz (after checking that timings

are in line with the target master).

Variable baud rate

t310

SSC clock cycle time (2)

Formula for SSC Clock Cycle time:

t310 = 4 TCL * (<SSCBR> + 1)

Where <SSCBR> represents the content of the SSC baud rate register, taken as unsigned 16-bit integer.

Minimum limit allowed for t310 is 125ns (corresponding to 8Mbaud).
