Bits 5, 6 – STALL Transmit Stall x Interrupt Flag

This flag is cleared by writing a one to the flag.

This flag is set when a Transmit Stall occurs and will generate an interrupt if EPINTENCLR/SET.STALL is one.

EPINTFLAG.STALL is set for a single bank OUT endpoint or double bank IN/OUT endpoint when current bank is "0".

Writing a zero to this bit has no effect.

Writing a one to this bit clears the STALL Interrupt Flag.

Bit 4 – RXSTP Received Setup Interrupt Flag

This flag is cleared by writing a one to the flag.

This flag is set when a Received Setup occurs and will generate an interrupt if EPINTENCLR/SET.RXSTP is one.

Writing a zero to this bit has no effect.

Writing a one to this bit clears the RXSTP Interrupt Flag.

Bits 2, 3 – TRFAIL Transfer Fail x Interrupt Flag

This flag is cleared by writing a one to the flag.

This flag is set when a transfer fail occurs and will generate an interrupt if EPINTENCLR/SET.TRFAIL is one.

EPINTFLAG.TRFAIL is set for a single bank OUT endpoint or double bank IN/OUT endpoint when current bank is "0".

Writing a zero to this bit has no effect.

Writing a one to this bit clears the TRFAIL Interrupt Flag.

Bits 0, 1 – TRCPT Transfer Complete x interrupt Flag

This flag is cleared by writing a one to the flag.

This flag is set when a Transfer complete occurs and will generate an interrupt if EPINTENCLR/SET.TRCPT is one. EPINTFLAG.TRCPT is set for a single bank OUT endpoint or double bank IN/OUT endpoint when current bank is "0".

Writing a zero to this bit has no effect.

Writing a one to this bit clears the TRCPT0 Interrupt Flag.
