Auto-normal function: if during hi-fi ‘playback’ mode no FM carrier is detected at FMIN (pin 37) the ‘Normal’ mode
audio signal (LININ; pin 21) is automatically selected by the output select function.
a) Hi-fi carrier detection time (i.e. auto-normal release time) can be selected via bit DETH:
‘fast’ mode: 1 to 2 HID periods (33 to 66 ms NTSC, 40 to 80 ms PAL)
‘slow’ mode: 7 to 8 HID periods (233 to 267 ms NTSC, 280 to 320 ms PAL).
b) The status of hi-fi detection can be monitored via the I
2
C-bus; see bit AUTN of the read byte (see Table 31).
c) If muting is required instead of automatic selection of the ‘Normal’ mode audio signal the normal input level
function should be set to mute; see bits NIL3 to NIL0 of the select byte.
