to logic 0. Comparator0 can also be programmed as a reset source; for details, see Section
Reset” on page 129.
The operation of Comparator1 is identical to that of Comparator0, though Comparator1 may not be configured as a
reset source. Comparator1 is controlled by the CPT1CN Register (Figure 11.4). The complete electrical specifications
for the Comparators are given in Table 11.1.
