Timer 3 Clock Select Register (T3CS)
Timer 3 Compare- and Compare Mode Register
Table 6-14.
Table 6-15.
Timer 3 has two separate compare registers T3CO1 and T3CO2 for the 8-bit stage of Timer 3.
The timer compares the content of the compare register with the current counter value. If both
match, it generates a signal. This signal can be used for the counter reset, to generate a timer
interrupt, for toggling the output flip-flop, as SSI clock or as clock for the next counter stage. For
each compare register, a compare-mode register exists. These registers contain mask bits to
enable or disable the generation of an interrupt, a counter reset, or an output toggling with the
occurrence of a compare match of the corresponding compare register. The mask bits for acti-
vating the single-action mode can also be located in the compare mode registers. When
assigned to the compare register a compare event will be suppressed.
