FS3-0: Sampling Frequency Select (Table 6 and Table 7) and MCKI Frequency Select (Table 12)
FS3-0 bits select sampling frequency at PLL mode and MCKI frequency at EXT mode.
BCKP: BICK Polarity at DSP Mode (Table 18)
“0”: SDTO is output by the rising edge (“
”) of BICK and SDTI is latched by the falling edge (“
”). (Default)
“1”: SDTO is output by the falling edge (“
”) of BICK and SDTI is latched by the rising edge (“
”).
MSBS: LRCK Polarity at DSP Mode (Table 18)
“0”: The rising edge (“
”) of LRCK is half clock of BICK before the channel change. (Default)
“1”: The rising edge (“
”) of LRCK is one clock of BICK before the channel change.
