Table 4 Bits IPAF and RAF
IPAF
RAF(1)
MODE
0 0 playback
1 0 loop-through
0 1 record(2)
1 1 record(2)
DESCRIPTION
NR and modem in playback mode
NR in record mode; modem not active [por]
NR and modem in record mode
NR and modem in record mode
Notes
1. The RAF bit can be overruled externally by applying a low-ohmic voltage to the RAF I/O (pin 14) either logic 0 or
logic 1 (0 or +5 V). The actual mode of the IC is determined by the level measured at this pin.
2. The two record modes are equal, only differing in their reaction to forcing RAF LOW at the RAF I/O pin; the status of
the IPAF bit determines whether the IC is switched to the playback or loop-through mode.

PB mute
DESCRIPTION
the signal from the modem is muted in playback mode
Note
1. Bit PAFM has the same effect as the internally generated mute signal from the modem part when no FM carrier is
detected during playback mode. If one (or both) of these signals is HIGH, the audio signal coming from the modem
is muted.
