2.7 PC/104 Bus Interrupts (Optional)
Interrupts to the PC/104 bus require the installation of the optional power management mircrocontroller (PM104). The PM104 can be programmed to provide indication of loss of input power, low battery voltage or to provide indication to the PC/104 CPU to begin an orderly shutdown of program operation.
Two separate interrupt requests can be generated and each interrupt request will remain active until the cause of the interrupt request returns to normal. Interrupt Int1 can be set to IRQ6 or IRQ7, while interrupt Int2 can be set to IRQ4 or IRQ5 by installing an appropriate jumper on jumper selections block J4. Jumper block J4 is located adjacent to the PC/104 bus on the opposite side where the power LEDs are located.
