Default = 00h
Function:
Default = 00h
Function:
The level of the left analog channel can be adjusted in 1 dB increments as dictated by the Soft and
Zero Cross bits (SZC[1:0]) from +15 to -15 dB. Levels are decoded in two’s complement, as shown
in Table 16.
The level of the right analog channel can be adjusted in 1dB increments as dictated by the Soft and
Zero Cross bits (SZC[1:0]) from +15 to -15dB. Levels are decoded in two’s complement, as shown in
Table 16.
Default = 0
0 - DAC & ADC Serial Port timings not in phase
1 - DAC & ADC Serial Port timings are in phase
Function:
Forces the LRCK and SCLK from the DAC & ADC Serial Ports to align and operate in phase. This
function will operate when both ports are running at the same sample rate or when operating at dif-
ferent sample rates.
