STA328
6.4
Configuration register D (addr 0x03)
Table 25.
The STA328 features an internal digital high-pass filter for the purpose of DC Blocking. The
purpose of this filter is to prevent DC signals from passing through a DDX
signals can cause speaker damage.
Table 26.
By setting this bit to 1, the de-emphasis will be implemented on all channels. DSPB (DSP
Bypass, Bit D2, CFA) bit must be set to 0 for de-emphasis to function.
Table 27.
Setting the DSPB bit bypasses all the EQ and mixing functionality of the STA328 core.
Table 28.
Post-scale functionality is an attenuation placed after the volume control and directly before
the conversion to PWM. Post-scale can also be used to limit the maximum modulation index
and therefore the peak current. A setting of 1 in the PSL register will result in the use of the
value stored in channel 1 post-scale for all three internal channels.
