Function Library: PCI-8154 + DB-8151
Type 2
: Generates hardware interrupt when any DI datas transi-
tion are detected and when the scan cycle is completed.
Figure 5-2: HSL DI Interrupt for Example#2
Type 3
: Generates hardware interrupt when any DI datas transi-
tion are detected and when the scan cycle is completed.When
interrupt occurred the scan will paused until driver reset the state.
Figure 5-3: HSL DI Interrupt for Example#3
Caution
: Scanning is paused while user choice the type3 of renewal
type. This pause time depends on the user system perfor-
mance. Consequently, when using type3, constancy(always
keeping scan cycle constant) will not be maintained between
scans.
