6.2.8 MATCH Function

The match output, which is useful for detecting when an event occurs, is set using an A > B comparator where:

A = the SSI data

B = the compare register

The MATCH output is set on an edge transition of the comparator output as follows:

When counting up: MATCH is set when A passes from (A<=B) to (A>B)

When counting down: MATCH is set when A passes from (A>B) to (A<=B)
