4.7.2.2 Compare Mode
The compare structure of T13 is based on the compare signals T13_ST_se (compare -
match detected) and T13_ST_re (zero-match detected without compare-match). These
compare signals may modify bit CC63ST only while the timer is running (T13R=’1’).

Similar to T12, bit CC63ST can be modified by SW by bits CC63S and CC63R. The
output line COUT63_T13_o can generate a T13 PWM at the output pin COUT63. The
signal MOD_T13_o can be used to modulate the other output signals with a T13 PWM.
In order to decouple COUT63 from the internal modulation, the compare state leading to
an active signal can be selected independently by bits T13IM and COUT63PS.
