* USBEN bit is reset by POR or LVI reset only.
Address:
USBEN — USB Module Enable
UADD[6:0] — USB Function Address
Reset:
Read:
Write:
This read/write bit enables and disables the USB module and the USB
pins. When USBEN is set, the USB module is enabled and the PTE4
interrupt is disabled. When USBEN is clear, the USB module will not
respond to any tokens, USB reset and USB related interrupts are
disabled, and pins PTE4/D– and PTE3/D+ function as high current
open-drain I/O port pins PTE4 and PTE3.
These bits specify the USB address of the device. Reset clears these
bits.
1 = USB function enabled and PTE4 interrupt is disabled
0 = USB function disabled including USB interrupt, reset and reset
