11.8 Stereodecoder Testmode
During the Testmode, which can be activated by setting bit D0 and bit D1 of the stereodecoder testing-byte,
several internal signals are available at the FD2R+ pin. During this mode the input resistance of 100kOhm is
disconnected from the pin. The internal signals available are shown in the Data-byte specification.
