USB on-the-go high-speed (OTG_HS)
OTG_HS device IN endpoint common interrupt mask register
(OTG_HS_DIEPMSK)
Address offset: 0x810
Reset value: 0x0000 0000
This register works with each of the Device IN endpoint interrupt (OTG_HS_DIEPINTx)
registers for all endpoints to generate an interrupt per IN endpoint. The IN endpoint interrupt
for a specific status in the OTG_HS_DIEPINTx register can be masked by writing to the
corresponding bit in this register. Status bits are masked by default.
