16.3.1 Main Control Register (MCNTRL)
The MCNTRL register controls the main functions of the
USB node. The MCNTRL register provides read/write ac-
cess from the CPU bus. Reserved bits must be written with
0, and they return 0 when read. It is clear after reset.

The USB Enable controls whether the USB
module is enabled. If the USB module is dis-
abled, the 48 MHz clock within the USB node
is stopped, all USB registers are initialized to
their reset state, and the USB transceiver forc-
es SE0 on the bus to prevent the hub from de-
tected the USB node. The USBEN bit is clear
after reset.
0 – The USB module is disabled.
