... Zero Data Detection Function Common to L/R The TC9444F incorporates a function to output a zero detection flag from the DZ pin when input data contain a string of digital zeros. This is used to forcibly mute the analog output. Table 2.4 shows the time that elapses until data are detected as zero data. If digital zeros continue to be output during this period, a zero detection flag is set. Moreover, setting the DZINH bit in the microcontroller interface mode command to “ ...
