USB INTERFACE (Cont’d)
11.3.5 Low Power modes
11.3.6 Interrupts
Note: The USB end of suspend interrupt event is connected to a single interrupt vector (USB ESUSP) with
the exit from halt capability (wake-up). All the other interrupt events are connected to another interrupt
vector: USB interrupt (USB). They generate an interrupt if the corresponding enable control bit is set and
the interrupt mask bits (I0, I1) in CC register are reset (RIM instruction).
Mode
HALT
WAIT
No effect on USB.
USB interrupt events cause the device to exit from WAIT mode.
USB registers are frozen.
In halt mode, the USB is inactive. USB operations resume when the MCU is woken up by an interrupt with
“exit from halt capability” or by an event on the USB line in case of suspend. This event will generate an
ESUSP interrupt which will wake-up from halt mode.
Suspend Mode Request
End of SUSPend mode.
