MODE2
When the write transmission of a state machine command starts during a mute state of the state machine,
the sequences of the state machine start immediately with the actions which follow the mute period in the
standard sequence (see
References to mute are only used for better understanding. Muting is performed in the IF DSP controlled by
the tuner AFHOLD and AFSAMPLE lines.
In the modes preset and search the AM AGC time constant is set to fast during the period of complete
mute.
The AF update sequence can also be started by pulling the AFHOLD pin LOW. In this case the AF
information should be loaded into the BUFFER before. LOW period for a correct AF update timing:
