2.10.3 Interrupt Function of the DI Signals
DI0 and DI1 can be used to generate hardware interrupts. Users can setup
the configuration of them by programming the interrupt control register.
The channels are connected to the interrupt circuitry. Users can disable/
enable interrupt function, select trigger type or latch the port data by set-
ting the Interrupt Control Register of the UNO-4672. When the interrupt
request signals occur, then the software will service these interrupt
requests by ISR (Interrupt Service Routine). The multiple interrupt
sources provide the card with more capability and flexibility.
2.10.4 IRQ Level
The IRQ level is by default set by the system BIOS. IRQ 7 is reserved for
DI interrupt and counter interrupt.
