Interrupt Configuration
Interrupt Configuration
The
EPM-CPU-10
has the standard complement of PC type interrupts. Ten non-shared interrupts are
routed to the PC/104 bus, and up to four IRQ lines are automatically allocated as needed to PCI
devices.
There are no interrupt configuration jumpers. All configuration is handled through CMOS setup.
The switches in the diagram below indicate the various CMOS Setup options. Closed switches
show factory default settings.
The temperature monitor interrupt and watchdog interrupt are enabled/disabled with the Special
Control Register.
Note
If your design needs to use interrupt lines on the PC/104 bus, we recommend using
IRQ5, IRQ9, and/or IRQ10.
