The values read from these Bits are always 0. Do not set these Bits.
Wake Up CPU Interrupt Flag
Set by hardware when the USB controller is in SUSPEND state and is re-activated
by a non-idle signal from USB line (not by an upstream resume). This triggers a USB
interrupt when EWUPCPU is set in the USBIEN.
Cleared by software after re-enabling all USB clocks.
End of Reset Interrupt Flag
Set by hardware when a End of Reset has been detected by the USB controller. This
triggers a USB interrupt when EEORINT is set in USBIEN.
Cleared by software.
Start of Frame Interrupt Flag
Set by hardware when a USB Start of Frame packet (SOF) has been properly
received. This triggers a USB interrupt when ESOFINT is set in USBIEN.
Cleared by software.
Reserved
The values read from these Bits are always 0. Do not set these Bits.
Suspend Interrupt Flag
Set by hardware when a USB Suspend (Idle bus for three frame periods: a J state for
3 ms) is detected. This triggers a USB interrupt when ESPINT is set in USBIEN.
Cleared by software.
WUPCPU
Function Enable Bit
Set to enable the function. The device firmware shall set this bit after it has
received a USB reset and participate in the following configuration process with
the default address (FEN is reset to 0).
Cleared by hardware at power-up, should not be cleared by the device firmware
once set.
USB Address Bits
This field contains the default address (0) after power-up or USB bus reset.
It shall be written with the value set by a SET_ADDRESS request received by
the device firmware.
