Bits of select byte

Table 9

Bits SAOL, SAOR and SAON; note 1

Note

1. The bits SAOL, SAOR and SAON provide eight output select functions, left and right are the left and right hi-fi

channels, normal is the conventional audio channel, linear audio input (LININ; pin 33).

Table 10 Bit HSF; note 1

Note

1. Normally the headphone outputs carry the same audio

signal as present at the line outputs

(LINEL and LINER), so the signal is selectable by

means of the bits SAOL, SAOR and SAON. However

when bit HSF is set HIGH, the headphone output has

its own output select function switchable with bits HSL

and HSR to stereo, left, right and normal

(see Section “Function byte”).

Table 11 Bit NSS; note 1

Note

1. Normally the bits NSH and NSL select one of the four

possible stereo line inputs (TUNL/R, CINL/R,

EXT1L/R, EXT2L/R) as the source signal for linear out.

Left and right channels of the selected input are added

to give a mono signal as output.

When bit NSS is set HIGH, four special input selects

can be made in combination with the same bits NSH

and NSL; volume controlled, tuner left (TUNL), EXN1

and EXN2 (see Section “Input byte”).
