0: The module is in USB host mode.
1: The module is in USB device mode.
This bit has no effect when UIDE is one (USB_ID input pin activated).
This bit can be written to even if USBE is zero or FRZCLK is one. Disabling the USBC (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 to even if USBE is zero or FRZCLK is one. Disabling the USBC (by writing a zero to the USBE bit) does
not reset this bit.
0: The TIMPAGE and TIMVALUE fields are locked.
1: The TIMPAGE and TIMVALUE fields are unlocked.
The TIMPAGE and TIMVALUE fields can always be read, regardless of the UNLOCK value.
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 disable the USBC, USB transceiver, and USB clock inputs. This will over-ride FRZCLK settings but
not affect the value. Unless explicitly stated, all registers will become reset and read-only.
Writing a one to this bit will enable the USBC.
0: The USBC is disabled.
