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)
