Description
This bit is used to set up square pixel mode. This is available in slave mode only. For NTSC, a
24.5454 MHz clock must be supplied. For PAL, a 29.5 MHz clock must be supplied.
These bits control the genlock feature of the ADV7174/ ADV7179. Setting MR21 to Logic 1
configures the SCRESET/RTC pin as an input. Setting MR22 to Logic 0 configures the
SCRESET/RTC pin as a subcarrier reset input. Therefore, the subcarrier will reset to Field 0
following a low-to-high transition on the SCRESET/RTC pin. Setting MR22 to Logic 1 configures
the SCRESET/RTC pin as a real-time control input.
This bit switches between two active video line durations. A 0 selects CCIR REC601 (720 pixels
PAL/NTSC), and a 1 selects ITU-R.BT470 standard for active video duration (710 pixels NTSC
and 702 pixels PAL).
This bit enables the color information to be switched on and off the video output.
This bit enables the burst information to be switched on and off the video output.
This bit enables the lower power mode of the ADV7174/ADV7179. This reduces the DAC
current by 45%.
A Logic 0 must be written to this bit.
