Chapter 3
Interrupts
The interrupt processing function executes an interrupt program when an external
input or request from the high-speed counter comparator (interrupt factor) is encoun-
tered during KV operation.
This chapter describes the types of interrupt factors as well as inputs and outputs
encountered during interrupt processing.
