The value read from this bit is always 0. Do not set this bit.
Reserved
The value read from this bit is always 0. Do not set this bit.
Endpoint 5 Interrupt
This bit is set by hardware when an endpoint interrupt source has been detected on the
endpoint 5. The endpoint interrupt sources are in the UEPSTAX register and can be:
TXCMP, RXOUTB0, RXOUTB1, RXSETUP or STLCRC.
A USB interrupt is triggered when the EP5IE bit in the UEPIEN register is set.
This bit is cleared by hardware when all the endpoint interrupt sources are cleared
Endpoint 4 Interrupt
This bit is set by hardware when an endpoint interrupt source has been detected on the
endpoint 4. The endpoint interrupt sources are in the UEPSTAX register and can be:
TXCMP, RXOUTB0, RXOUTB1, RXSETUP or STLCRC.
A USB interrupt is triggered when the EP4IE bit in the UEPIEN register is set.
This bit is cleared by hardware when all the endpoint interrupt sources are cleared
Endpoint 3 Interrupt
This bit is set by hardware when an endpoint interrupt source has been detected on the
endpoint 3. The endpoint interrupt sources are in the UEPSTAX register and can be:
TXCMP, RXOUTB0, RXOUTB1, RXSETUP or STLCRC.
A USB interrupt is triggered when the EP3IE bit in the UEPIEN register is set.
This bit is cleared by hardware when all the endpoint interrupt sources are cleared
Endpoint 2 Interrupt
This bit is set by hardware when an endpoint interrupt source has been detected on the
endpoint 2. The endpoint interrupt sources are in the UEPSTAX register and can be:
TXCMP, RXOUTB0, RXOUTB1, RXSETUP or STLCRC.
A USB interrupt is triggered when the EP2IE bit in the UEPIEN register is set.
This bit is cleared by hardware when all the endpoint interrupt sources are cleared
Endpoint 1 Interrupt
This bit is set by hardware when an endpoint interrupt source has been detected on the
endpoint 1. The endpoint interrupt sources are in the UEPSTAX register and can be:
TXCMP, RXOUTB0, RXOUTB1, RXSETUP or STLCRC.
A USB interrupt is triggered when the EP1IE bit in the UEPIEN register is set.
This bit is cleared by hardware when all the endpoint interrupt sources are cleared
Endpoint 0 Interrupt
This bit is set by hardware when an endpoint interrupt source has been detected on the
endpoint 0. The endpoint interrupt sources are in the UEPSTAX register and can be:
TXCMP, RXOUTB0, RXOUTB1, RXSETUP or STLCRC.
A USB interrupt is triggered when the EP0IE bit in the UEPIEN register is set.
This bit is cleared by hardware when all the endpoint interrupt sources are cleared
