20.17 Interrupts
7707F–AVR–11/10
It is not possible to have overflow error during IN stage, in the CPU side, since the CPU should
write only if the bank is ready to access data (TXINI=1 or RWAL=1).
The next figure shows all the interrupts sources:
Figure 20-4. USB Device Controller Interrupt System
There are 2 kind of interrupts: processing (i.e. their generation are part of the normal processing)
and exception (errors).
Processing interrupts are generated when:
Exception Interrupts are generated when:
• Upstream resume(UPRSMI)
• End of resume(EORSMI)
• Wake up(WAKEUPI)
• End of reset (Speed Initialization)(EORSTI)
• Start of frame(SOFI, if FNCERR=0)
• Suspend detected after 3 ms of inactivity(SUSPI)
• CRC error in frame number of SOF(SOFI, FNCERR=1)
