Audioprocessor testing
During the testmode, which can be activated by setting bit D₀ of the stereo decoder testing
byte and the audioprocessor 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.
