Stop - Read/Write
The STOP value is the value of the Vertical down counter
at which the VBLANKn signal becomes inactive (stops).
This is used to generate the BLANKn signal that is used
by external devices and indicates the end of the active
video portion for the Vertical frame. Please refer to video
signalling timing diagrams in
VBLANKn is an internal block signal. The NBLANK output
is a logical AND of NVBLANK and HBLANKn.
