Hi.

 

I have a question about USB interrupt.

 

Under conditions of follows, At the time of USB connect,Interrupt (USBSTS = 0x00000080) of SRI of the USB is called.

 

I use a USB device.

I enable ARM GIC(USBC0).

USB0_USBINTR=0;


Q1)In the case of an interrupt of the USB, may the interrupt that I do not enable occur?

Q2)Please tell me the work around of the case.


Best Regards,

Soichi
