Audio Interface Format
Data is shifted in/out the SDTI/SDTO pins using BCLK and LRCK inputs. The serial data is MSB-first, 2's compliment
format, ADC is MSB justified and DAC is LSB justified.

Control Register Timing
The data on the 3-wire serial interface consists of op-code (3bit), address (LSB-first, 5bit) and control data (LSB-first,
8bit). The Transmitting data is output to each bit by “
↓
” of CCLK, the receiving data is latched by “
↑
” of CCLK. Writing
data becomes effective by “
↑
” of CS . CS should be held to “H” at no access.
CCLK always need 16 edges of “
↑
” during CS = “L” Address except 00H
～
0BH are inhibited.
Writing of the control registers are invalid when op2-0 bits are except “111”.
