(32) UF0 GPR register (UF0GPR)
UF0GPR
Bit position
This register controls USBF and the USB interface.
This register is write-only, in 8-bit units. If this register is read, 00H is read. Be sure to clear bits 7 to 1 to “0”.
FW can reset the USBF by writing 1 to bit 0 of this register. This bit is automatically cleared to 0 after 1 has
been written to it. Writing 0 to this bit is invalid.

CHAPTER 22 USB FUNCTION CONTROLLER (USBF)
Set this bit to 1 to reset USBF.
Actually, USBF is reset two USB clocks after this bit has been set to 1 by FW and the
write signal has become inactive.
Resetting USBF by the MRST bit while the system clock is operating has the same result
as resetting by the RESET pin (hardware reset) (register value back to default value).
However, the UF0CS and UF0BC registers are not reset by the MRST bit.
