RM0090 USB on-the-go full-speed (OTG_FS)
OTG_FS device all endpoints interrupt register (OTG_FS_DAINT)
Address offset: 0x818
Reset value: 0x0000 0000
When a significant event occurs on an endpoint, a OTG_FS_DAINT register interrupts the
application using the Device OUT endpoints interrupt bit or Device IN endpoints interrupt bit
of the OTG_FS_GINTSTS register (OEPINT or IEPINT in OTG_FS_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_FS_DIEPINTx/OTG_FS_DOEPINTx).
