High-speed Counter Function

10.5 Interrupt Program Activation

10.5.1 Overview of Function

When the elapsed value reaches the target value while the high-speed counter instruction
F165 (CAM0)/F166 (HC1S)/F167 (HC1R) is being executed, the interrupt program can be
activated.
 Execution method
• Make the setting for the high-speed counter by system registers. There is no need to make
the setting of interrupt input.
• Describe the interrupt program as a sub program.
• Allow the execution of a corresponding interrupt program number by the ICTL instruction in
the main program.
• Execute the F165 (CAM0)/F166 (HC1S)/F167 (HC1R) instruction. When the elapsed value
of the high-speed counter reaches the target value, the interrupt program is activated.
