The value read from these bits is always 0. Do not change this bit.
Endpoint 6 Interrupt
This bit is set by hardware when an interrupt has been detected on the endpoint 6.
The interrupt sources are part of UEPSTAX register and can be : TXCMP,
RXOUTB0, RXOUTB1, RXSETUP or STLCRC. A USB interrupt is triggered when
the EP6INTE bit in the UEPIEN register is set.
This bit is cleared by hardware when all the interrupt sources are cleared.
Endpoint 5 Interrupt
This bit is set by hardware when an interrupt has been detected on the endpoint 5.
The interrupt sources are part of UEPSTAX register and can be : TXCMP,
RXOUTB0, RXOUTB1, RXSETUP or STLCRC. A USB interrupt is triggered when
the EP5INTE bit in the UEPIEN register is set.
This bit is cleared by hardware when all the interrupt sources are cleared.
Endpoint 4 Interrupt
This bit is set by hardware when an interrupt has been detected on the endpoint 4.
The interrupt sources are part of UEPSTAX register and can be : TXCMP,
RXOUTB0, RXOUTB1, RXSETUP or STLCRC. A USB interrupt is triggered when
the EP4INTE bit in the UEPIEN register is set.
This bit is cleared by hardware when all the interrupt sources are cleared.
Endpoint 3 Interrupt
This bit is set by hardware when an interrupt has been detected on the endpoint 3.
The interrupt sources are part of UEPSTAX register and can be : TXCMP,
RXOUTB0, RXOUTB1, RXSETUP or STLCRC. A USB interrupt is triggered when
the EP3INTE bit in the UEPIEN register is set.
This bit is cleared by hardware when all the interrupt sources are cleared.
Endpoint 2 Interrupt
This bit is set by hardware when an interrupt has been detected on the endpoint 2.
The interrupt sources are part of UEPSTAX register and can be : TXCMP,
RXOUTB0, RXOUTB1, RXSETUP or STLCRC. A USB interrupt is triggered when
the EP2INTE bit in the UEPIEN register is set.
This bit is cleared by hardware when all the interrupt sources are cleared.
Endpoint 1 Interrupt
This bit is set by hardware when an interrupt has been detected on the endpoint 1.
The interrupt sources are part of UEPSTAX register and can be : TXCMP,
RXOUTB0, RXOUTB1, RXSETUP or STLCRC. A USB interrupt is triggered when
the EP1INTE bit in the UEPIEN register is set.
This bit is cleared by hardware when all the interrupt sources are cleared.
Endpoint 0 Interrupt
This bit is set by hardware when an interrupt has been detected on the endpoint 0.
The interrupt sources are part of UEPSTAX register and can be : TXCMP,
RXOUTB0, RXOUTB1, RXSETUP or STLCRC. A USB interrupt is triggered when
the EP0INTE bit in the UEPIEN register is set.
This bit is cleared by hardware when all the interrupt sources are cleared.
