Compare match interrupt
Compare match interrupt
This is an application example where two compare registers are used in the free-running timer mode.
The TO00 output level is reversed each time the count value of TM00 matches the set value of CR000 or CR010.
When the count value matches the register value, the INTTM000 or INTTM010 signal is generated.
