Autoswitch mode:
0 = Stand-alone (forced video standard) mode
1 = Autoswitch mode
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.
