Bit 2 – TRFAIL0: Transfer Fail 0 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.TRFAIL0 is one.
EPINTFLAG.TRFAIL0 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 TRFAIL0 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.TRFAIL0 is one.
EPINTFLAG.TRFAIL0 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 TRFAIL0 Interrupt Flag.
z
Bit 1 – TRCPT1: Transfer Complete 1 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.TRCPT1 is
one. EPINTFLAG.TRCPT1 is set for a single bank IN endpoint or double bank IN/OUT endpoint when current
bank is "1".
Writing a zero to this bit has no effect.
Writing a one to this bit clears the TRCPT1 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.TRCPT1 is
one. EPINTFLAG.TRCPT1 is set for a single bank IN endpoint or double bank IN/OUT endpoint when current
bank is "1".
Writing a zero to this bit has no effect.
Writing a one to this bit clears the TRCPT1 Interrupt Flag.
