This bit has no effect when UIDE is one (USB_ID input pin activated).
0: The module is in USB host mode.
1: The module is in USB device mode.
This bit can be written even if USBE is zero or FRZCLK is one. Disabling the USBB (by writing a zero to the USBE bit) does not
reset this bit.
0: The USB mode (device/host) is selected from the UIMOD bit.
1: The USB mode (device/host) is selected from the USB_ID input pin.
This bit can be written even if USBE is zero or FRZCLK is one. Disabling the USBB (by writing a zero to the USBE bit) does not
reset this bit.
1: The TIMPAGE and TIMVALUE fields are unlocked.
0: The TIMPAGE and TIMVALUE fields are locked.
The TIMPAGE and TIMVALUE fields can always be read, whatever the value of UNLOCK.
This field contains the page value to access a special timer register.
This field selects the timer value that is written to the special time register selected by TIMPAGE. See
details.
Writing a zero to this bit will reset the USBB, disable the USB transceiver and, disable the USBB clock inputs. Unless explicitly
stated, all registers then will become read-only and will be reset.
1: The USBB is enabled.
0: The USBB is disabled.
