OTG_FS host channel-x interrupt register (OTG_FS_HCINTx) (x = 0..7, where
x = Channel_number)
Address offset: 0x508 + (Channel_number × 0x20)
Reset value: 0x0000 0000
This register indicates the status of a channel with respect to USB- and AHB-related events.
It is shown in
interrupt bit in the Core interrupt register (HCINT bit in OTG_FS_GINTSTS) is set. Before
the application can read this register, it must first read the Host all channels interrupt
(OTG_FS_HAINT) register to get the exact channel number for the Host channel-x interrupt
register. The application must clear the appropriate bit in this register to clear the
corresponding bits in the OTG_FS_HAINT and OTG_FS_GINTSTS registers.
Bit 10 DTERR: Data toggle error
Bit 9 FRMOR: Frame overrun
Bit 8 BBERR: Babble error
Bit 7 TXERR: Transaction error
Bit 6 Reserved
Bit 5 ACK: ACK response received/transmitted interrupt
Bit 4 NAK: NAK response received interrupt
Bit 3 STALL: STALL response received interrupt
Bit 2 Reserved
Bit 1 CHH: Channel halted
Bit 0 XFRC: Transfer completed
Indicates one of the following errors occurred on the USB.
Indicates the transfer completed abnormally either because of any USB transaction error or in
response to disable request by the application.
Transfer completed normally without any errors.
