Description
This bit specifies if the part is in composite video or RGB/YPbPr mode.
This bit enables the output from the RGB DACs to be set to YPbPr output video standard.
This bit is used to set up the RGB outputs with the sync information encoded on all RGB
outputs.
When this bit is enabled (1) in slave mode, it is possible to drive the VSYNC active low
input for 2.5 lines in PAL mode and three lines in NTSC mode. When this bit is enabled in
master mode, the ADV7174/ADV7179 outputs an active low VSYNC signal for three lines
in NTSC mode and 2.5 lines in PAL mode.
This bit specifies whether a pedestal is to be generated on the NTSC composite video
signal. This bit is invalid if the ADV7174/ ADV7179 is configured in PAL mode.
This bit controls the filter mode applied outside the active video portion of the line. This
filter ensures that the sync rise and fall times are always on spec regardless of which luma
filter is selected. A Logic 1 enables this mode.
When this bit is set (1), sleep mode is enabled. With this mode enabled, the
ADV7174/ADV7179 power consumption is reduced to typically 200 nA. The I
2
C registers
can be written to and read from when the ADV7174/ADV7179 is in sleep mode. If MR46 is
set to a (0) when the device is in sleep mode, the ADV7174/ADV7179 comes out of sleep
mode and resumes normal operation. Also, if the RESET signal is applied during sleep
mode, the ADV7174/ADV7179 comes out of sleep mode and resumes normal operation.
A Logic 0 should be written to this bit.
