Interrupt
Name
When change in VBUS input pin status is detected
(Low to High or High to Low):
[Detects Host connect/disconnect when Peripheral Controller function
is selected.]
When change in USB bus is detected in suspend state (J-State to
K-State, J-State to SEO state):
[Detects resume when Peripheral Controller function is selected.]
When SOF packet with different frame number is sent
When transition in device state is detected:
When transition in control transfer stage is detected:
When all data in buffer memory is sent and buffer is empty
When a packet is received that is bigger than maxpacket size
<When Host Controller Function is selected>
STALL is received from peripheral side
No-response from peripheral side is detected 3 times
Overrun/underrun is detected during Isochronous transfer
<When Peripheral Controller Function is selected>
Token is received when “PID=BUF” is set and buffer memory is in a
state that does not allow transfers
CRC error or bit stuff error occurs during Isochronous data receive
When FIFO buffer goes to Ready (read or write enabled state)
When OCVMON bit of related port changes state
[When Host Controller Function is selected, use to connect each of
OVCR0A, OVCR0B and OVCR1 pins to overcurrent status indicated
pins of VBUS supply power switch, and use to detect overcurrent for
each port]
When USB bus state change is detected:
[When Host Controller Function is selected, use to detach ports in
suspend status and detect remote wakeup]
When Peripheral Device detach is detected
When Peripheral Device attach is detected
When EOF error is detected on corresponding port
When setup transaction error (no response, ACK packet corrupted) is
detected
When normal response (ACK) is received for setup transaction
p a g e 1 1 6 o f 1 8 3
Detects USB bus reset
Detects suspend state
Receives Set Address request
Receives Set Configuration request
Completes setup stage
Transitions to control write transfer status stage
Transitions to control read transfer status stage
Completes control transfer
Generates control transfer sequence error
