The tuner is controlled by the I
control of the tuning action via the bits MODE[2:0] and REGC and subaddressing via bits
SA[3:0] (see
The tuner circuit is controlled by the CONTROL register. Any data change in the
CONTROL register has immediate effect and will change the operation of the tuner circuit
accordingly. The subaddress range 00h to 05h includes data that may lead to audible
disturbance when changed. Therefore the subaddress range 00h to 05h is not loaded in
the CONTROL register directly but loaded in a BUFFER register instead. This allows the
IC to take care of tuning actions and mute control, freeing the microcontroller from
cumbersome controls and timings. The subaddress range of 06h to 0Fh does not contain
such critical data. I
CONTROL register directly (at acknowledge of each byte).
Controlled by a state machine the BUFFER data will be loaded in the CONTROL register
for new settings. However at the same time the CONTROL data is loaded in the BUFFER
register. This register swap action allows a fast return to the previous setting because the
previous data remains available in the BUFFER register (see
Via MODE several operational modes can be selected for the state machine. MODE offers
all standard tuning actions as well as generic control for flexibility. The state machine
controls the tuner by controlling I
mute. Action progress is monitored by the accompanying signal processor via the
AFSAMPLE and AFHOLD lines, this way functions like weak signal processing can be
controlled complementary to the tuner action.
