This read-only bit is set when an overflow has occurred on the 13-bit
vertical frequency counter. Reset clears this bit, and will be updated
every vertical frame.
An overflow occurs when the period of Vsync frame exceeds
64.768ms (a vertical frame frequency lower than 15.258Hz).
VFR
1 = A vertical frequency counter overflow has occurred
0 = No vertical frequency counter overflow has occurred
