Description

USB Device FIQ select

Fields

FRAME

This interrupt comes from a 1 KHz free running clock resynchronized on the incoming SoF tokens. This is to be used for isochronous packet transfer.

0 (LOWPRIORITY): FRAME interrupt will be routed to the low-priority interrupt line IRQ.

1 (HIGHPRIORITY): FRAME interrupt will be routed to the high-priority interrupt line FIQ.

BULKOUT

Interrupt routing for bulk out endpoints For logical endpoint 3 (physical endpoints 6 and 7) only.

0 (LOWPRIORITY): BULKOUT interrupt will be routed to the low-priority interrupt line IRQ.

1 (HIGHPRIORITY): BULKOUT interrupt will be routed to the high-priority interrupt line FIQ.

BULKIN

Interrupt routing for bulk in endpoints For logical endpoint 3 (physical endpoints 6 and 7) only.

0 (LOWPRIORITY): BULKIN interrupt will be routed to the low-priority interrupt line IRQ.

1 (HIGHPRIORITY): BULKIN interrupt will be routed to the high-priority interrupt line FIQ.
