USB interrupt status register

Fields

EP0OUT	Interrupt status register bit for the Control EP0 OUT direction. This bit will be set if NBytes transitions to zero or the skip bit is set by software or a SETUP packet is successfully received for the control EP0. If the IntOnNAK_CO is set, this bit will also be set when a NAK is transmitted for the Control EP0 OUT direction. Software can clear this bit by writing a one to it.
EP0IN	Interrupt status register bit for the Control EP0 IN direction. This bit will be set if NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_CI is set, this bit will also be set when a NAK is transmitted for the Control EP0 IN direction. Software can clear this bit by writing a one to it.
EP1OUT	Interrupt status register bit for the EP1 OUT direction. This bit will be set if the corresponding Active bit is cleared by HW. This is done in case the programmed NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_AO is set, this bit will also be set when a NAK is transmitted for the EP1 OUT direction. Software can clear this bit by writing a one to it.
EP1IN	Interrupt status register bit for the EP1 IN direction. This bit will be set if the corresponding Active bit is cleared by HW. This is done in case the programmed NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_AI is set, this bit will also be set when a NAK is transmitted for the EP1 IN direction. Software can clear this bit by writing a one to it.
EP2OUT	Interrupt status register bit for the EP2 OUT direction. This bit will be set if the corresponding Active bit is cleared by HW. This is done in case the programmed NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_AO is set, this bit will also be set when a NAK is transmitted for the EP2 OUT direction. Software can clear this bit by writing a one to it.
EP2IN	Interrupt status register bit for the EP2 IN direction. This bit will be set if the corresponding Active bit is cleared by HW. This is done in case the programmed NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_AI is set, this bit will also be set when a NAK is transmitted for the EP2 IN direction. Software can clear this bit by writing a one to it.
EP3OUT	Interrupt status register bit for the EP3 OUT direction. This bit will be set if the corresponding Active bit is cleared by HW. This is done in case the programmed NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_AO is set, this bit will also be set when a NAK is transmitted for the EP3 OUT direction. Software can clear this bit by writing a one to it.
EP3IN	Interrupt status register bit for the EP3 IN direction. This bit will be set if the corresponding Active bit is cleared by HW. This is done in case the programmed NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_AI is set, this bit will also be set when a NAK is transmitted for the EP3 IN direction. Software can clear this bit by writing a one to it.
EP4OUT	Interrupt status register bit for the EP4 OUT direction. This bit will be set if the corresponding Active bit is cleared by HW. This is done in case the programmed NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_AO is set, this bit will also be set when a NAK is transmitted for the EP4 OUT direction. Software can clear this bit by writing a one to it.
EP4IN	Interrupt status register bit for the EP4 IN direction. This bit will be set if the corresponding Active bit is cleared by HW. This is done in case the programmed NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_AI is set, this bit will also be set when a NAK is transmitted for the EP4 IN direction. Software can clear this bit by writing a one to it.
EP5OUT	Interrupt status register bit for the EP5 OUT direction. This bit will be set if the corresponding Active bit is cleared by HW. This is done in case the programmed NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_AO is set, this bit will also be set when a NAK is transmitted for the EP5 OUT direction. Software can clear this bit by writing a one to it.
EP5IN	Interrupt status register bit for the EP5 IN direction. This bit will be set if the corresponding Active bit is cleared by HW. This is done in case the programmed NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_AI is set, this bit will also be set when a NAK is transmitted for the EP5 IN direction. Software can clear this bit by writing a one to it.

This is done in case the programmed NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_AI is set, this bit will also be set when a NAK is transmitted for the EP6 IN direction. Software can clear this bit by writing a one to it.
EP7OUT	Interrupt status register bit for the EP7 OUT direction. This bit will be set if the corresponding Active bit is cleared by HW. This is done in case the programmed NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_AO is set, this bit will also be set when a NAK is transmitted for the EP7 OUT direction. Software can clear this bit by writing a one to it.
EP7IN	Interrupt status register bit for the EP7 IN direction. This bit will be set if the corresponding Active bit is cleared by HW. This is done in case the programmed NBytes transitions to zero or the skip bit is set by software. If the IntOnNAK_AI is set, this bit will also be set when a NAK is transmitted for the EP7 IN direction. Software can clear this bit by writing a one to it.
FRAME_INT	Frame interrupt. This bit is set to one every millisecond when the VbusDebounced bit and the DCON bit are set. This bit can be used by software when handling isochronous endpoints. Software can clear this bit by writing a one to it.
DEV_INT	Device status interrupt. This bit is set by HW when one of the bits in the Device Status Change register are set. Software can clear this bit by writing a one to it.
