bit 6 UNDEF Un_define bit
[0]: Input signal detected

fixed bit
[1]: No input signal detected
Input signal detection phase3:
[0]: Input signal search in progress
[1]: Input signal search complete
*If input signal is identified as SECAM, ST_VSCF[1:0] changes to [11].
1Monochrome auto detection is enabled if the color killer setting is ON(COLKILL-bit = [1]).
ST_BW-bit changes to [1] when the color killer operates.
If the user has deliberately entered the B/W-bit setting Sub Address 0x01, input signal detection
is limited to 525/625 line detection, and only the ST_VLF information is relevant.
2Shows results of input signal detection.
If an input signal is detected, the value is [0]; if no input signal is detected, the value is [1].
3Shows the operating phase of the automatic input signal detector.
The value is [0] while the detection operation is in progress, and [1] when it is completed;
thus, when UNDEF-bit = [1], FIXED-bit = [0].
