Preliminary specification
Audio processor for VHS hi-fi
and linear audio
TDA9614H
Table 17
Bits OSL, OSR and OSN; note 1
Note
1.
The bits OSL, OSR and OSN provide eight output select functions. LEFT and RIGHT are the left and right hi-fi
channels; NORMAL is the linear audio channel (LININ; pin 28). This selection is normally output at line out (LINEL
and LINER), RFCOUT (pin 18), decoder out (LINE2L and LINE2R), headphone out (HPOUTL and HPOUTR) and
DC out (DCOUTL and DCOUTR). However line out can be overruled by bits LOS1 and LOS0; decoder out can be
overruled by bits DOS1 and DOS0, headphone out (and DC out) can be overruled by bits HSL and HSR and DC out
can be overruled by bit DCS.
Remark:
if AUTN = 1 (see Section 6.11) the output select modes stereo, left and right will be forced to normal as long
as the audio FM circuit is in playback mode and the internal PB mute signal is generated (no hi-fi track on tape). The
status of this internal mute signal can be read by bit PAFM (see Section 6.13).
