USB2.0_INTR—USB 2.0 Interrupt Enable Register
Offset:
Default Value:
This register enables and disables reporting of the corresponding interrupt to the software. When a
bit is set and the corresponding interrupt is active, an interrupt is generated to the host. Interrupt
sources that are disabled in this register still appear in the USB2.0_STS Register to allow the
software to poll for events. Each interrupt enable bit description indicates whether it is dependent
on the interrupt threshold mechanism (see Section 4 of the Enhanced Host Controller Interface
Specification for Universal Serial Bus, Revision 1.0, or not.

0 = Disable
1 = Enable. When this bit is a 1, and the USBINT bit in the USB2.0_STS register is a 1, the host
register is a 1, the host controller will issue an interrupt at the next interrupt threshold. The
interrupt is acknowledged by software clearing the Interrupt on Async Advance bit.
