During a preset and search tuning the tuner is always muted, this is done by the algorithm
itself. When bit AHLSI is set and the tuner stopped during a preset or a search because of
a wrong IF count, the tuner stays muted and generates an interrupt event. In this way the
host processor can switch the Hi-Lo setting quietly and wait for the new result.
All these mute actions are done by blocking the audio signal inside the soft mute
attenuator, so the audio output will keep its DC level and stay low-ohmic i.e. 350
mute with bit MU will cause a plop) (see
The first two bytes of the I
flags. A flag is set when it is 1.
The interrupt flag register contains the flags set according to the behavior outlined in
Section
(HW) interrupt line] depending on the status of the corresponding mask bit in
logic 1 in the mask register enables the HW interrupt for that flag.
Hence it is conceivable that, with all the mask bits cleared, the SoftWare (SW) could
operate in a polling mode by continuous read operation of the interrupt flag register to look
for bits being set.
Interrupt mask bits are always cleared after reading the interrupt register of the first two
