Writing a 1 to this bit will soft-reset the HW_USBPHY_PWD, HW_USBPHY_TX,
HW_USBPHY_RX, and HW_USBPHY_CTRL registers.
Gate UTMI Clocks. Clear to 0 to run clocks. Set to 1 to gate clocks. Set this to save power while
the USB is not actively being used. Configuration state is kept while the clock is gated.
Note this bit can be auto-cleared if there is any wakeup event when USB is suspended while
ENAUTOCLR_CLKGATE bit of HW_USBPHY_CTRL is enabled.
Used by the PHY to indicate a powered-down state. If all the power-down bits in the
HW_USBPHY_PWD are enabled, UTMI_SUSPENDM will be 0, otherwise 1. UTMI_SUSPENDM
is negative logic, as required by the UTMI specification.
Forces the next FS packet that is transmitted to have a EOP with low-speed timing. This bit is
used in host mode for the resume sequence. After the packet is transferred, this bit is cleared.
The design can use this function to force the LS SE0 or use the
HW_USBPHY_CTRL_UTMI_SUSPENDM to trigger this event when leaving suspend. This bit
is used in conjunction with HW_USBPHY_DEBUG_HOST_RESUME_DEBUG.
Reserved.
Enables the feature to auto-clear the EN_USB_CLKS register bits in
HW_CLKCTRL_PLL1CTRL0/HW_CLKCTRL_PLL1CTRL1 if there is wakeup event on USB0/USB1
while USB0/USB1 is suspended.This should be enabled if needs to support auto wakeup without
S/W's interaction.
