TV RGB Mute
x0xxxxxx
x1xxxxxx
TV RGB OUTPUTS ARE ACTIVE
TV RGB outputs are mute (Blank level)
RGB Sync Source
0xxxxxxx RGB sync /DC restore source = RGB
1xxxxxxx RGB sync /DC restore source = Aux_YC or Enc_YC depending on source selection

Description
Function Control Output
Voltage
xxxxxx00 Level 0; normal TV output (Function Voltage ~ 0V)
xxxxxx01 Level 1A; 16:9 aspect ratio (Function Voltage ~ 6V)
xxxxxx10 Level 1B; Peritelevision output mode (Function Voltage ~ 12V)
xxxxxx11 Level 1B; Peritelevision output mode (Function Voltage ~ 12V)
xxxx00xx Aux_Fnc pin = output, TV_Fnc pin = output
Function Pin Control*
xxxx01xx Aux_Fnc pin = output, TV_Fnc pin = input
xxxx10xx Aux_Fnc pin = input,
TV_Fnc pin = output
xxxx11xx Signals will pass through from Aux_Fnc to TV_Fnc or vice versa.
The voltage applied to this pin (when set as an input) sets the state of the
two LSBs of the read register. See the note*
xx00xxxx RGB output amplifier gain = normal
xx01xxxx RGB output amplifiers attenuated by 10%
xx10xxxx RGB output amplifiers attenuated by 20%
xx11xxxx RGB output amplifiers attenuated by 30%
00xxxxxx BLANK = ABLANK
RGB Gain Control
BLANK output selection
01xxxxxx BLANK = EBLANK
10xxxxxx BLANK = 0V
11xxxxxx BLANK = 4V @ IC output pin
* Function pin voltages: (I) in output mode, are defined by the two LSBs of register 2, (II) in input mode, set the
state of the two LSBs of the read register.
Digital read is not meaningful in the pass-through mode( xxxx11xx ).
** Aux_Cin is not available on the 48 QFN package option.
*** Not available in the 48 QFN package option.
