Figure 4-4: USB controller write timing
The ISP1761 controller can drive two interrupts.
IRQ1 is the HC_IRQ from the ISP1761 controller.
IRQ3 is the DC_IRQ output from the ISP1761 controller. DC_IRQ interrupts can be enabled on the HC_IRQ pin,
so this can be disabled for host RSKs with fewer interrupt lines, if the DC_IRQ interrupt is required.
Both interrupts are pulled high to 3.3V by 1K resistors.
