Video standard
Sampling rate
This register contains information about the detected video standard and the sampling rate at which the device
is currently operating. When autoswitch code is running, this register must be tested to determine which video
standard has been detected.
Autoswitch mode:
0 = Stand-alone (forced video standard) mode
1 = Autoswitch mode
