6.19.4 Muting during search or preset
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
(a hard
mute with bit MU will cause a plop) (see Table 3).

Interrupt handling
7.1 Interrupt register
The rst two bytes of the I2C-bus register contain the interrupt masks and the interrupt
ags. A ag is set when it is 1.
The interrupt ag register contains the ags set according to the behavior outlined in
Section 7.1.4. When these are set they can also cause the INTX to go active [HardWare
(HW) interrupt line] depending on the status of the corresponding mask bit in Table 6. A
logic 1 in the mask register enables the HW interrupt for that ag.
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 ag register to look
for bits being set.
Interrupt mask bits are always cleared after reading the interrupt register of the rst two
