Details of video microprocessor related information /
<1st byte: Image delay time>
Displays the setting time of the Audio Delay offset value.
(HEX)
Example) 37 = 55msec
<2nd byte: I2C communication error>
Displays the I2C error condition using the bit unit. (HEX)
bit 0 = TA1318 communication error (1: an error exists)
bit 1 = XV750B communication error (1: an error exists)
bit 2 = FLI2310 communication error (1: an error exists)
bit 3 = ADV7310 communication error (1: an error exists)
bit 4 = Error at device initialization (1: an error exists)
Example) 00 = 0b00000000
<3rd byte: Image MUTE trigger>
Displays the image MUTE trigger (cause) immediately be-
fore.
01 = Change in internal synchronization/external synchro-
nization
02 = Change in color system, resolution or aspect conver-
sion
03 = Change of path from analog bypass to digital process-
ing system
04 = Input change
05 = Input change
06 = Start mode for video P.C.B. alone
07 = Immediately after power ON
08 = Change in decoders in use (MN673744, XV750B)
<4th byte: Image MUTE information>
Displays the current image MUTE information. (HEX)
bit 0 = VCR1 REC OUT MUTE (1: muting being executed)
bit 1 = VCR2 REC OUT MUTE (1: muting being executed)
bit 2 = DVR REC OUT MUTE (1: muting being executed)
bit 3 = MONITOR OUT MUTE (1: muting being executed)
bit 4 = ZONE2 MUTE (1: muting being executed)
bit 5 = REC OUT SOURCE select (1: SOURCE select)
bit 6 = MUTE by ADV7310 DAC Power OFF (1: muting be-
ing executed)
Example) 20 = 0b00100000
