information on interrupt servicing.)
Edge-sensitive interrupts require pulsewidths greater than 10 ns; level-sensitive interrupts must be held low until serviced.
IRQx = IRQ0, IRQ1, IRQ2, IRQL0, IRQL1, IRQLE.
PFx = PF0, PF1, PF2, PF3, PF4, PF5, PF6, PF7.
Flag Outputs = PFx, FL0, FL1, FL2, Flag_out4.
