USB Suspend Mode

MCU Power Modes
The processing general interrupts are:
The exception general interrupts are:
In peripheral mode, the Suspend Interrupt bit in the Device Global Interrupt register
(UOTGHS_DEVISR.SUSP) indicates that the USB line is in suspend mode. In this case, the
transceiver is automatically set in suspend mode to reduce the consumption.
The UOTGHS can be frozen when the USB line is in the suspend mode, by writing a one to the
UOTGHS_CTRL.FRZCLK bit, which reduces the power consumption.
In this case, it is still possible to access the following elements:
Moreover, when UOTGHS_CTRL.FRZCLK is written to one, only the asynchronous interrupt
sources may trigger the USB interrupt:
• The ID Transition Interrupt (UOTGHS_SR.IDTI)
• The VBus Transition Interrupt (UOTGHS_SR.VBUSTI)
• The SRP Interrupt (UOTGHS_SR.SRPI)
• The Role Exchange Interrupt (UOTGHS_SR.ROLEEXI)
• The VBus Error Interrupt (UOTGHS_SR.VBERRI)
• The B-Connection Error Interrupt (UOTGHS_SR.BCERRI)
• The HNP Error Interrupt (UOTGHS_SR.HNPERRI)
• The Suspend Time-Out Interrupt (UOTGHS_SR.STOI)
• The UOTGHS_CTRL.OTGPADE, UOTGHS_CTRL.VBUSPO, UOTGHS_CTRL.FRZCLK,
• The ID Transition Interrupt (UOTGHS_SR.IDTI)
• The VBus Transition Interrupt (UOTGHS_SR.VBUSTI)
• The Wake-up Interrupt (UOTGHS_DEVISR.WAKEUP)
• The Host Wake-up Interrupt (UOTGHS_HSTISR.HWUPI)
UOTGHS_CTRL.USBE, UOTGHS_CTRL.UIDE, UOTGHS_CTRL.UIMOD and
UOTGHS_DEVCTRL.LS bits
