FMTA1-0: PCM I/F A Format (Table 117)
Default: “00” (Mode 0)
LAWA1-0: PCM I/F A Mode (Table 115)
Default: “00” (Mode 0)
BCKPA: P BICKA Polarity of PCM I/F A (Table 119)
“0”: SDTOA is output by the rising edge (“↑”) of BICKA and SDTIA is latched by the falling edge (“↓”). (default)
“1”: SDTOA is output by the falling edge (“↓”) of BICKA and SDTIA is latched by the rising edge (“↑”).
MSBSA: SYNCA Phase of PCM I/F A (Table 119)
“0”: The rising edge (“↑”) of SYNCA is half clock of BICKA before the channel change. (default)
“1”: The rising edge (“↑”) of SYNCA is one clock of BICKA before the channel change.
SDOAD: SDTOA Disable (Table 96)
“0”: Enable (default)
