NOTE
The trace clock frequency observed at the TRACE_CLKOUT
pin will be half that of the selected clock source.
5.7.4 PORT digital filter clocking
The digital filters in each of the PORTx modules can be clocked as shown in the
following figure.
NOTE
In stop mode, the digital input filters are bypassed unless they
are configured to run from the 1 kHz LPO clock source.
