10
EP1
Logic 1 indicates the interrupt source: endpoint 1.
9
EP0IN
Logic 1 indicates the interrupt source: control IN endpoint.
8
EP0OUT
Logic 1 indicates the interrupt source: control OUT endpoint.
7
BUSTATUS
It monitors the current USB bus status (0 = awake, 1 = suspend).
6
SP_EOT
Logic 1 indicates that an EOT interrupt has occurred for a short packet.
5
PSOF
Logic 1 indicates that an interrupt is issued every 1 ms because of the
pseudo SOF; after three missed SOFs, the suspend state is entered.
4
SOF
Logic 1 indicates that a SOF condition was detected.
3
EOT
Logic 1 indicates that an internal EOT condition was generated by the
DMA counter reaching zero.
2
SUSPND
Logic 1 indicates that an awake to suspend change of state was detected
on the USB bus.
1
RESUME
Logic 1 indicates that a resume state was detected.
0
RESET
Logic 1 indicates that a bus reset condition was detected.
