(1) The USB core supports global over-current reporting. This bit reflects the state of the OVRCUR pin dedicated to this port. This bit is only
valid if the No Over-current Protection (MEMOFST 49h[4]) bit is cleared and Over-current Protection Mode (MEMOFST 49h[3]) bit is set.
(2) If the Device Removable bits (MEMOFST 4Ch[15:0]) are set (not removable), bit 0 is always 1.
