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
The level of the right 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
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.
