endpoints only.
Bit 3 STUPM: STUPM: SETUP phase done mask. Applies to control endpoints only.
Bit 2 Reserved, must be kept at reset value.
Bit 1 EPDM: Endpoint disabled interrupt mask
Bit 0 XFRCM: Transfer completed interrupt mask

33.15.35 OTG device all endpoints interrupt register (OTG_DAINT)

Address offset: 0x818
Reset value: 0x0000 0000
When a significant event occurs on an endpoint, a OTG_DAINT register interrupts the
application using the device OUT endpoints interrupt bit or device IN endpoints interrupt bit
of the OTG_GINTSTS register (OEPINT or IEPINT in OTG_GINTSTS, respectively). 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-x interrupt register (OTG_DIEPINTx/OTG_DOEPINTx).
