DEVICE OUT ENDPOINT COMMON INTERRUPT MASK REGISTER (DOEPMSK)
This register works with each of the Device OUT Endpoint Interrupt registers for all endpoints to generate an
interrupt per OUT endpoint. The OUT endpoint interrupts for a specific status in the DOEPINTn register can be
masked by writing to the corresponding bit in this register. Status bits are masked by default.

DEVICE ALL ENDPOINTS INTERRUPT REGISTER (DAINT)
When a significant event occurs on an endpoint, a Device All Endpoints Interrupt register interrupts the application
using the Device OUT Endpoints Interrupt bit or Device IN Endpoints Interrupt bit of the Core Interrupt register.
There is one interrupt bit per endpoint, up to a maximum of 16 bits for OUT endpoints and 16 bits for IN
endpoints. For a bidirectional endpoint, the corresponding IN and OUT interrupt bits are used. Bits in this register
are set and cleared when the application sets and clears bits in the corresponding Device Endpoint – n Interrupt
register.
