6.3.4 Timer- and Compare-Register Configurations of the CCU
The compare function and the reaction of the corresponding outputs depend on the timer/compare
register combination. Table 6-5 shows the possible configurations of the CCU and the
corresponding compare modes which can be selected. The following sections describe the function
of these configurations.
