A signal selection for output ENVOUT (pin 39) is available using bit EOS.
POR.
The selection made for mode ‘Stereo or HF envelope’ depends upon the mode of the hi-fi processing:
a) Hi-fi ‘loop-through’ mode or ‘record’ mode (bit AFM = 1): audio peak envelope of hi-fi stereo.
b) Hi-fi ‘playback’ mode (bit AFM = 0): HF envelope of left channel FM carrier.

Bit LOS; notes 1 and 2
Notes
1.
An independent selection of EXT2L and EXT2R inputs (pins 7 and 8) to the line outputs LINEL and LINER
(pins 15 and 16) is possible by setting bit LOS to 1. This direct selection is also operable in ‘a(chǎn)ctive standby’ mode
(STBA = 1 of the control byte).
Using bit DOS and bits DOS1 and DOS0 of the output byte mode ‘Tuner’ or ‘Ext1’ selection to the outputs DECL and
DECR (pins 18 and 19) is offered realizing full Euro-SCART pay-TV decoder switching.
