Interrupts
Figure 62 shows all the device interrupts sources while Figure 63 details the endpoint
interrupt sources.
Figure 62. USB Device Controller Interrupt System
There are 2 kinds of interrupts: processing (i.e. their generation are part of the normal
processing) and exception (errors).
Processing interrupts are generated when the following events are triggered:
VBUSTI: VBUS plug-in detection (insert, remove)
UPRSMI: upstream resume
EORSMI: end of resume
WAKEUPI: Wake up
EORSTI: end of reset (Speed Initialization)
SOFI: start of frame (FNCERR= 0)
MSOFI: micro start of frame (FNCERR= 0)
SUSPI: suspend detected after 3 ms of inactivity
Exception Interrupts are generated when the following events are triggered:
SOFI: CRC error in frame number of SOF (FNCERR= 1)
MSOFI: CRC error in frame number of micro-SOF (FNCERR= 1)
