6.5.3 High Speed Output Mode
In this mode the CEX output (on port 1) associated with the PCA module will toggle each time a match
occurs between the PCA counter and the module's capture registers. To activate this mode the TOG, MAT,
and ECOM bits in the module's CCAPMn SFR must be set (See Figure 11.).
A prior write must be done to CCAPnL and CCAPnH before writing the ECOMn bit.
Figure 11. PCA High Speed Output Mode
Before enabling ECOM bit, CCAPnL and CCAPnH should be set with a non zero value, otherwise an unwanted
match could happen.
Once ECOM set, writing CCAPnL will clear ECOM so that an unwanted match doesn’t occur while modifying
the compare value. Writing to CCAPnH will set ECOM. For this reason, user software should write CCAPnL first,
and then CCAPnH. Of course, the ECOM bit can still be controlled by accessing to CCAPMn register.
