Hi TI：

can I dynamically disable USB （as a device）bulk enpoint rx interrupt for a really short time，meanwhile this operation will not affect the bulk enpoint rx process and data validaty？

Is there already an function for this？

Thanks

Hello Yao,

You can do so for a specific endpoint with:

USBIntDisableEndpoint(uint32_t ui32Base, uint32_t ui32Flags)

//! \param ui32Base specifies the USB module base address.
//! \param ui32Flags specifies which endpoint interrupts to disable.

Then you can re-enable with:

USBIntEnableEndpoint(uint32_t ui32Base, uint32_t ui32Flags)
