OTG_FS device IN endpoint common interrupt mask register
(OTG_FS_DIEPMSK)
Address offset: 0x810
Reset value: 0x0000 0000
This register works with each of the Device IN endpoint interrupt (OTG_FS_DIEPINTx)
registers for all endpoints to generate an interrupt per IN endpoint. The IN endpoint interrupt
for a specific status in the OTG_FS_DIEPINTx register can be masked by writing to the
corresponding bit in this register. Status bits are masked by default.
Bit 3 EERR: Erratic error
Bit 0 SUSPSTS: Suspend status
Bit 9 BIM: BNA interrupt mask
Bit 8 TXFURM: FIFO underrun mask
Bit 7 Reserved
The core sets this bit to report any erratic errors.
Due to erratic errors, the OTG_FS controller goes into Suspended state and an interrupt is
generated to the application with Early suspend bit of the Core interrupt register (ESUSP bit in
OTG_FS_GINTSTS). If the early suspend is asserted due to an erratic error, the application
can only perform a soft disconnect recover.
Indicates the speed at which the OTG_FS controller has come up after speed detection
through a chirp sequence.
In Device mode, this bit is set as long as a Suspend condition is detected on the USB. The core
enters the Suspended state when there is no activity on the USB data lines for a period of
3 ms. The core comes out of the suspend:
– When there is an activity on the USB data lines
– When the application writes to the Remote wakeup signaling bit in the Device control register
01: Reserved

Others: reserved
(RWUSIG bit in OTG_FS_DCTL).
