Output Compare - Fujitsu F2MC-16LX Hardware Manual

CHAPTER 12 16-BIT INPUT/OUTPUT TIMER

12.2.2 Output compare

Output compare consists of a 16-bit compare register, compare output pin section,
and control register. If the compare register of this module and the 16-bit free-running
timer have matching values, the output level of the pin may be reversed and an
interrupt may be generated.
• A total of six compare registers are provided, and each operates independent of the
other.
With their settings, the two compare registers are used to control output.
• Interrupt can be specified with compare matching.

Note:
To rewriting the compare register, within the compare interrupt routine or compare operation
is disabled. Be sure not to occur simultaneously a compare match and writing the compare
register.
