10. Comparators
Two on-chip programmable voltage comparators are included, as shown in Figure 10.1. The inputs of each
comparator are available at dedicated pins. The output of each comparator is optionally available at the
package pins via the I/O crossbar. When assigned to package pins, each comparator output can be pro-
grammed to operate in open drain or push-pull modes. See
Priority Crossbar Decoder” on page 238
