23.16 Overflow
In Control, Isochronous, Bulk or Interrupt Endpoint, an overflow can occur during OUT stage, if
the host attempts to write in a bank that is too small for the packet. In this situation, the OVERFI
interrupt is triggered (if enabled). The packet is acknowledged and the RXOUTI interrupt is also
triggered (if enabled). The bank is filled with the first bytes of the packet.
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).
23.17 Interrupts
Figure 23-8 shows all the interrupts sources.
Figure 23-8. USB device controller interrupt system.
There are two kinds of interrupts: processing (that is, their generation are part of the normal pro-
cessing) and exception (errors).
Processing interrupts are generated when:
VBUS plug-in detection (insert, remove)(VBUSTI)
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 3ms of inactivity(SUSPI)
Exception Interrupts are generated when:
CRC error in frame number of SOF(SOFI, FNCERR=1)
