STALLEDI: STALLed Interrupt
CRCERRI: CRC Error Interrupt
OVERFI: Overflow Interrupt
NAKINI: NAKed IN Interrupt
NAKOUTI: NAKed OUT Interrupt
UNDERFI: Underflow Interrupt
This bit is set to signal that a STALL handshake has been sent. To do that, the software has to set the STALLRQ bit (by writing a
This bit is cleared when the STALLEDIC bit is written to one. This will acknowledge the interrupt.
This bit is set to signal that a CRC error has been detected in an isochronous OUT endpoint. The OUT packet is stored in the
This bit is cleared when the CRCERRIC bit is written to one. This will acknowledge the interrupt.
This bit is set when an overflow error occurs. This triggers an EPnINT interrupt if OVERFE is one.
For all endpoint types, an overflow can occur during OUT stage if the host attempts to write into a bank that is too small for the
This bit is cleared when the OVERFIC bit is written to one. This will acknowledge the interrupt.
This bit is set when a NAK handshake has been sent in response to an IN request from the host. This triggers an EPnINT
This bit is cleared when the NAKINIC bit is written to one. This will acknowledge the interrupt.
This bit is set when a NAK handshake has been sent in response to an OUT request from the host. This triggers an EPnINT
This bit is cleared when the NAKOUTIC bit is written to one. This will acknowledge the interrupt.
This bit is set, for isochronous IN/OUT endpoints, when an underflow error occurs. This triggers an EPnINT interrupt if
An underflow can occur during IN stage if the host attempts to read from an empty bank. A zero-length packet is then
An underflow can also occur during OUT stage if the host sends a packet while the bank is already full. Typically, the CPU is not
