2.3
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 “H” halts zero
detection, fixing the DZ pin to “L” and disabling the zero detection function (see the microcontroller
interface section below).

A reset sets the DZ signal to “H”.

Data Output Formats
Table 2.5 and Figure 2.2 show the data output formats. Microcontroller interface bits OBIT
1
and
OBIT2 select the format.
In master mode, the BCKI clock rate varies through the range shown in Table 2.2. Note, however,
that BCKO is fixed to 64 fs.
In slave mode, the BCKI input clock is directly output as the data output bit clock (BCKO) through
the IC internal buffer (see section 2.2).
