The bits of this register indicate the interrupt source, defining the events that determined
the INT generation. Clearing the bits that were set because of the events listed is done by
writing back logic 1 to the respective position. All bits must be reset before enabling new
interrupt events. These bits will be set, regardless of the setting of bit GLOBAL_INTR_EN
in the HW Mode Control register.

Description
reserved; write logic 0
ISO IRQ: Indicates that an IRQ was asserted because an ISO PTD was
completed, or the PTDs corresponding to the bits set in the ISO IRQ
Mask AND or ISO IRQ Mask OR register bits combination were
completed.
0 — No IRQ assertion determined by the completion of ISO PTDs
1 — IRQ asserted because of completing ISO PTDs.
For details, see
ATL IRQ: Indicates that an IRQ was asserted because an ATL PTD was
completed, or the PTDs corresponding to the bits set in the ATL IRQ
Mask AND or ATL IRQ Mask OR register bits combination were
completed.
0 — No IRQ assertion determined by the completion of ATL PTDs
1 — IRQ asserted because of completing ATL PTD.
