GD32F10x User Manual Applies to non-periodic IN endpoints only. This interrupt is triggered on a endpoint for which an IN token was received when the associated Tx FIFO (periodic/non-periodic) was empty. 3 TOC Timeout condition Applies only to control IN endpoints. Indicates that the core has detected a timeout condition on the USB for the last IN token on this endpoint. 1 EPDISIF Endpoint disabled interrupt flag Indicates that the endpoint is disabled according to the application’s request. 0 XFIF Transfer finished interrupt flag Indicates that the programmed transfer is finished on the AHB as well as on the USB, for this endpoint. OTG_FS Device OUT endpoint-n interrupt flag register (OTG_FS_DOEPnIFR) (n = 0..3, where n = endpoint_number) Address offset: 0x0B08 + (endpoint_number × 0x20) Reset value: 0x0000 0000 This register indicates the status of an endpoint with respect to USB- and AHB-related events. The application must read this register when the OUT endpoints Interrupt flag bit (OEPIF) of the OTG_FS_GIFR register is set. Before the application can read this register, it must first read the OTG_FS_DAEPINT register to get the exact endpoint number. The application must clear the appropriate bit in this register to clear the corresponding bits in the OTG_FS_DAEPINT and OTG_FS_GIFR registers. 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 6 5 4 3 2 1 0 Reserved 15 14 13 12 11 10 SETUP EPDISIF XFIF Fields 7 OTREPD Bits 8 BTBSETUP Reserved 9 rc_w1 rc_ rc_ rc_ rc_w /rw w1 w1 w1 1 Res Res Descriptions 834
