Description
Level 0; normal TV output (Function Voltage = 0V)
Level 1A; 16:9 aspect ratio (Function Voltage = 6V)
Level 1B; Peritelevision output mode (Function Voltage = 11V)
Level 1B; Peritelevision output mode (Function Voltage = 11V)
Aux_Fnc pin = output, TV_Fnc pin = output
Aux_Fnc pin = output, TV_Fnc pin = input
Aux_Fnc pin = input, TV_Fnc pin = output
Signals will pass through from Aux_Fnc to TV_Fnc or vice versa.
RGB output amplifier gain = normal
RGB output amplifiers attenuated by 10%
RGB output amplifiers attenuated by 20%
RGB output amplifiers attenuated by 30%
BLANK = ABLANK
BLANK = EBLANK
BLANK = 0V
BLANK = 4V @ IC output pin
* Function pin voltages: (I) in output mode are defined by the two LSB of register 2, (II) in input mode set the
state of the two LSB of the read register.
Digital read is not meaningful in the pass-through mode( xxxx11xx ).
Register 3: Audio control register B

Bits Description
D0 output control
xxxxxxx0 D0 output = 0 (low)
xxxxxxx1 D0 output = 1 (high)
D1 output control
xxxxxx0x D1 output = 0 (low)
xxxxxx1x D1 output = 1 (high)
Not used
xxxx00xx Reserved, set to 0 for normal operation
TV Stereo/mono control xx00xxxx TV audio mode: stereo
xx01xxxx TV audio mode: mono (sum L+R) on both TV_Lout/TV_Rout
xx10xxxx TV audio mode: L channel on both TV_Lout/TV_Rout
xx11xxxx TV audio mode: R channel on both TV_Lout/TV_Rout
