Figure 3.16.16 Operation of suspend/remote wakeup signals
The int_suspend_resume interrupt occurs by detecting the suspended state on
the USB bus.
By the int_suspend_resume interrupt, the interrupt source is cleared and the
phy_suspend bit of Power Detect Control register is set to 1 by software.
Setting the phy_suspend bit will assert the PHYSUSPEND_X output signal to 0
which will stop the supply of CLK_U.
When requesting remote wakeup, set the <phy_remote_wkup> bit of Power
Detect Control register to 1. Setting the phy_remote_wkup bit will cause UDC2
to make a remote wakeup request on the USB bus. Also, suspend_x will be
deasserted to 1 asynchronously.
Deasserting suspend_x will cause the int_suspend_resume interrupt to occur
and the PHYSUSPEND_X output signal to be deasserted to 1.
Deasserting the PHYSUSPEND_X output signal will resume CLK_U. The
phy_remote_wkup bit will be automatically cleared.
Clears the int_suspend_resume interrupt source.
