Setting this register to 1, STA013 leaves the idle
state, starting the decoding process.
The Microcontroller is allowed to set the RUN
flag, once all the control registers have been in-
itialized.

The registers BASS_FREQUENCY_HIGH and
BASS_FREQUENCY_LOW, logically concate-
nated as a 16 bit wide register, are used to select
the frequency, in Hz, where the selected fre-
quency is -12dB respect to the pass-band. By
setting the BASS_FREQUENCY registers, the
following rules must be kept:

The registers TREBLE_FREQUENCY-HIGH and
TREBLE_FREQUENCY-LOW, logically concate-
nated as a 16 bit wide register, are used to select
the frequency, in Hz, where the selected fre-
quency is +12dB respect to the stop band.
By setting these registers, the following rule must
be kept:
Treble_Freq < Fs/2
Bass_Freq <= Treble_Freq
Bass_Freq > 0
(suggested range: 20 Hz < Bass_Freq < 750 Hz)
Example:
Bass = 200Hz
Treble = 3kHz
