d. <suspend_x>
e. <phy_suspend>
f.
This bit is used to perform the remote wakeup function of USB. Setting this bit to 1 makes
it possible to assert the udc2_wakeup output signal (wakeup input pin of UDC2) to 1.
However, since setting this bit to 1 while no suspension is detected by UDC2 (when
suspend_x = 1) will be ignored (not to be set to 1), be sure to set it only when suspension is
detected. It will be automatically cleared to 0 when resuming the USB is completed (when
suspend_x is deasserted).
See also section 3.16.2.13 “(4) Signal operations when suspended and resumed
(disconnected)" for more information on using this bit.
0y0: No operation
0y1: Wakeup
<phy_resetb>
Setting this bit to 0 will make the PHYRESET output signal asserted to 1. The
PHYRESET signal can be used to reset PHY. Since this bit will not be automatically
released, be sure to clear it to 1 after the specified reset time of PHY.
0y0: Reset asserted
0y1: Reset deasserted
Detects the suspend signal (a value of the suspend_x signal from UDC2 synchronized).
0y0: Suspended (suspend_x = 0)
0y1: Unsuspended (suspend_x = 1)
Setting this bit to 1 will make the PHYSUSPEND output signal asserted to 0 (CLK_H
synchronization). It can be used as a pin for suspending PHY.
Setting this bit to 1 makes the UDC2 register and DMAC Read Request register not
accessible.
It will be automatically cleared to 0 when resumed (when suspend_x of UDC2 is
deasserted).
See also section 3.16.2.13 “(4) Signal operations when suspended and resumed
(disconnected)” for more information on using this bit.
0y0: Not suspended
0y1: Suspended
<pw_detect>
Indicates the status of the VBUSPOWER input pin.
0y0: USB bus disconnected (VBUSPOWER = 0)
0y1: USB bus connected (VBUSPOWER = 1)
Note: While UDC2AB originally has the function to assert the int_powerdetect interrupt when VBUS is
detected, it is not supported for this LSI. Power Detect Control<pw_detect> always indicates 0.
