Notes on Suspend Operation
Clock control in suspend operation
USB 2.0 PHY clock control
Internal registers during the suspend state
When the SuspendM input (UTMI) to USB 2.0 PHY is enabled at suspend, the clock
supply from PHY to UDC2 is stopped. If UDC2 needs to use the clock from PHY after
suspend_x becomes “L”, supend_x should not be directly connected to PHY. The
SuspendM input to PHY should be enabled after the system determines that the clock
supply from PHY can be stopped.
(When the clock input (30 MHz) to UDC2 is stopped, the internal registers of UDC2
cannot be accessed across PVCI-I/F and Endpoint-I/F.)
The SuspendM input (UTMI) to USB 2.0 PHY should not be directly connected to the
suspend_x output of UDC2. It should be controlled by the system. As explained earlier,
suspend_x of UDC2 is activated by communication with the USB host. Therefore, if the
USB host is not connected, suspend_x retains the hardware reset value of “H”. At this
time, if suspend_x and SuspendM are directly connected, the clock supply from USB 2.0
PHY is not stopped and system power consumption cannot be saved.
During the suspend state, UDC2 retains the internal register values, the contents of
FIFOs, and the state of each flag. These values and states are also retained after the
suspend state is exited by resume operation.
