Freescale Semiconductor
The USB module is capable of generating interrupts and causing the
CPU to execute the USB interrupt service routine. There are three types
of USB interrupts:
All USB interrupts share the same interrupt vector. Firmware is
responsible for determining which interrupt is active.
There are five possible end-of-transaction interrupts:
End-of-transaction interrupts occur as detailed in the following sections.
•
•
•
•
•
End-of-transaction interrupts signify either a completed
transaction receive or transmit transaction.
Resume interrupts signify that the USB bus is reactivated after
having been suspended.
End-of-packet interrupts signify that a low-speed end-of-packet
signal was detected.
Endpoint 0 or 2 receive
Endpoint 0, 1 or 2 transmit
