int_suspend_resume interrupt

int_powerdetect interrupt
Figure 3.16.14 Operation of suspend/disconnect signals (when CLK_H is stopped)
Signal operation of Figure 3.16.13 and Figure 3.16.14:
2.5 s after the interrupt is asserted (time required for the signal to stabilize when
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 by software
and the phy_suspend bit of Power Detect Control register is set to 1.
Setting the phy_suspend bit will assert the PHYSUSPEND_X output signal to 0
which will stop the supply of CLK_U.
After setting the wakeup_en bit of Power Detect Control register to 1 by software,
CLK_H can be stopped.
By detecting Resume on the USB bus or disconnecting (VBUS disconnected), the
WAKEUP_X output signal will be asserted to 0 asynchronously.
Supply of CLK_H is started by the WAKEUP_X output signal. With the supply of
CLK_H, the int_suspend_resume or the int_powerdetect interrupts will occur.
(If the rise of suspend_x is detected, the PHYSUSPEND_X output signal will be
automatically deasserted.)
VBUS is disconnected), check the pw_detect bit of the Power Detect Control
register.
