TDA7406
During the Testmode, which can be activated by setting bit I2 of the subaddress byte 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
