Interrupt Functions Section 5-1
Scheduled interrupt 2 is executed every 30.5 ms.
5-1-5 High-speed Counter Interrupts
This function executes the specified interrupt task (0 to 255) when the CP1H
CPU Unit’s built-in high-speed counter PV matches a pre-registered value
(target value comparison) or lies within a pre-registered range (range compar-
ison).
• CTBL(882) is used to register the comparison table.
• Either CTBL(882) or INI(880) can be used to start comparison.
• INI(880) is used to stop comparison.
For details on the built-in high-speed counter, refer to 5-2 High-speed
Counters.
