29.15.36 OTG device IN endpoint common interrupt mask register
(OTG_DIEPMSK)
Address offset: 0x810
Reset value: 0x0000 0000
This register works with each of the OTG_DIEPINTx registers for all endpoints to generate
an interrupt per IN endpoint. The IN endpoint interrupt for a specific status in the
OTG_DIEPINTx register can be masked by writing to the corresponding bit in this register.
Status bits are masked by default.
