7-3 High-speed Counter Interrupts
A high-speed counter interrupt counts input pulses with the built-in high-speed counter and executes an
interrupt task when the count reaches the preset value or falls within a preset range (target-value or
range comparison). An interrupt task between 0 and 255 can be allocated with the CTBL(882) instruc-
tion.
