1. When entering a sleep mode deeper or equal to DeepStop, the VBus asynchronous interrupt can not be triggered because
the bandgap voltage reference is off. Thus this interrupt should be disabled (USBCON.VBUSTE = 0).
MCU Power modes
•Run mode
•Idle mode
•Frozen mode
•Standby, Stop, DeepStop and Static modes
•USB clock frozen
The exception general interrupts are:
In this mode, all MCU clocks can run, including the USB clock.
In this mode, the CPU is halted, i.e. the CPU clock is stopped. The Idle mode is entered what-
ever the state of the USBB. The MCU wakes up on any USB interrupt.
Same as the Idle mode, except that the HSB module is stopped, so the USB DMA, which is an
HSB master, can not be used. Moreover, the USB DMA must be stopped before entering this
sleep mode in order to avoid erratic behavior. The MCU wakes up on any USB interrupt.
Same as the Frozen mode, except that the USB generic clock and other clocks are stopped, so
the USB macro is frozen. Only the asynchronous USB interrupt sources can wake up the MCU
in these modes
nous wake up from USB. The USB module must be frozen by writing a one to the FRZCLK bit.
In the run, idle and frozen MCU modes, the USBB can be frozen when the USB line is in the sus-
pend mode, by writing a one to the FRZCLK bit, what reduces power consumption.
In deeper MCU power modes (from StandBy mode), the USBC must be frozen.
In this case, it is still possible to access the following elements, but only in Run mode:
• The ID Transition Interrupt (IDTI)
• The VBus Transition Interrupt (VBUSTI)
• The Role Exchange Interrupt (ROLEEXI)
• The VBus Error Interrupt (VBERRI)
• The B-Connection Error Interrupt (BCERRI)
• The Suspend Time-Out Interrupt (STOI)
• The OTGPADE, VBUSPO, FRZCLK, USBE, UIDE, UIMOD and LS bits in the USBCON
• The DPRAM (through the USB Pipe/Endpoint n FIFO Data (USBFIFOnDATA) registers, but
register
not through USB bus transfers which are frozen)
