When a function pin is set as an output, the output

level for the pin is determined by the state of the two

LSBs Register 2, according to the following table:

Dual SCART A/V Switch

The function output circuit includes short circuit

protection. When a function pin is in the 6V or 11V

output mode, if the SCART connection is shorted to

ground, then the output is disabled. Likewise, when

a function pin is in the 0V output mode, if the

SCART connection is connected to a voltage

source, then the output is disabled. The load for the

function outputs is designed to be 10k or higher.

Note that both the Aux_Fnc pin and the TV_Fnc pin

can be set as outputs simultaneously, however they

will have the same output voltage.
