OTG_FS device OUT endpoint common interrupt mask register
(OTG_FS_DOEPMSK)
Address offset: 0x814
Reset value: 0x0000 0000
This register works with each of the OTG_FS_DOEPINTx registers for all endpoints to
generate an interrupt per OUT endpoint. The OUT endpoint interrupt for a specific status in
the OTG_FS_DOEPINTx register can be masked by writing into the corresponding bit in this
register. Status bits are masked by default.
Bit 5 INEPNMM: IN token received with EP mismatch mask
0: Masked interrupt
1: Unmasked interrupt
Bit 4 ITTXFEMSK: IN token received when TxFIFO empty mask
0: Masked interrupt
1: Unmasked interrupt
Bit 3 TOM: Timeout condition mask (Non-isochronous endpoints)
0: Masked interrupt
1: Unmasked interrupt
Bit 2 Reserved, must be kept at reset value.
Bit 1 EPDM: Endpoint disabled interrupt mask
0: Masked interrupt
1: Unmasked interrupt
Bit 0 XFRCM: Transfer completed interrupt mask
0: Masked interrupt
1: Unmasked interrupt
