Example of a Suspend/Resume Management

Upstream Resume
A USB device can be allowed by the Host to send an upstream resume for Remote Wake-up
purpose.
When the USB controller receives the SET_FEATURE request: DEVICE_REMOTE_WAKEUP,
the firmware should set to 1 the RMWUPE bit in the USBCON register to enable this functional-
ity. RMWUPE value should be 0 in the other cases.
If the device is in SUSPEND mode, the USB controller can send an upstream resume by clear-
ing first the SPINT bit in the USBINT register and by setting then to 1 the SDRMWUP bit in the
USBCON register. The USB controller sets to 1 the UPRSM bit in the USBCON register. All
clocks must be enabled first. The Remote Wake is sent only if the USB bus was in Suspend
state for at least 5ms. When the upstream resume is completed, the UPRSM bit is reset to 0 by
hardware. The firmware should then clear the SDRMWUP bit.
