45.4.7 OTG Status Register (USBx_OTGSTAT)
The OTG Status Register displays the actual value from the external comparator outputs
of the ID pin and VBUS.
Addresses: USB0_OTGSTAT is 4007_2000h base + 18h offset = 4007_2018h

ONEMSECEN
This bit is reserved for the 1msec count, but it is not useful to software.
5
This bit indicates that the internal signals that control the LINE_STATE_CHG bit (bit 5) of the
LINESTATESTABLE OTGISTAT register have been stable for at least 1 millisecond. First read the LINE_STATE_CHG bit,
and then read this bit. If this bit reads as 1, then the value of LINE_STATE_CHG can be considered
stable.
