C-bus control
TDA8745
Table 15
Bit PE; Port Extension; note 1
Note
1.
Two IF inputs (IN-5 and IN-6; pins 7 and 8) can be used as digital output instead. If no more than four IF inputs are
needed, two external functions can be controlled via the I
2
C-bus this way. The level at these pins is controlled by
bits IL2 (i7) and IR2 (i4); see Tables 7 and 8.

Bits OML and OMR; Output Mute Left and Output Mute Right; note 1
Note
1.
Left and right audio can be muted independently. Note that also the external input signals (pins 25 and 24) can be
muted this way.
