The serial channel ASC has its own dedicated 13-bit baudrate generator with 13-bit
reload capability, allowing baudrate generation independent of the GPT timers.
The baudrate generator is clocked with a clock (f
the ASC input clock f
can be started or stopped through the baudrate generator run bit S0CON_R. Each
underflow of the timer provides one clock pulse to the serial channel. The timer is
reloaded with the value stored in its 13-bit reload register each time it underflows. The
resulting clock f
asynchronous modes and ± 4 in synchronous mode). The prescaler is selected by the
bits S0CON_BRS and S0CON_FDE. In the asynchronous operating modes, additionally
to the two fixed dividers a fractional divider prescaler unit is available which allows to
select prescaler divider ratios of n/512 with n=0-511. Therefore, the baudrate of ASC is
