DESCRIPTION
TV Input Reference Current Setting.
An external resistor (Rset) should be connected between this pin and
VSSA_VDAC to set the reference current of the video DAC. The value
of the resistor depends on the mode of operation.

–
In Normal mode (internal amplifier used), the nominal value for Rset
VDDA_VDAC_1P8 ^{is 4700 Ω.}
In TVOUT Bypass mode (internal amplifier not used), the nominal
value for Rset is 10000 Ω.
When the TV output is not used, this pin should be connected to
ground (VSS).
