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.
1: The USBC is enabled.
This bit can be written to even if FRZCLK is one.
Writing a zero to this bit will enable USB clock inputs.
Writing a one to this bit will disable USB clock inputs. The resume detection will remain active. Unless explicitly stated, all
registers will become read-only.
0: The clock inputs are enabled.
1: The clock inputs are disabled.
This bit can be written to even if USBE is zero.
