Baud Rate Generation
The Baud rate generator is clocked by f
stopped through the global enable bit SSCEN in register SSCCON. Register SSCBR is the dual-function
Baud Rate Generator/Reload register. Reading SSCBR, while the SSC is enabled, returns the content of
the timer. Reading SSCBR, while the SSC is disabled, returns the programmed reload value. In this mode
the desired reload value can be written to SSCBR.
Note
The formulas below calculate the resulting Baud rate for a given reload value and the required reload
value for a given Baud rate:
(SSCBR) represents the content of the reload register, taken as unsigned 16-bit integer.
Table 25 lists some possible Baud rates against the required reload values and the resulting bit times for
a 32MHz CPU clock.
