MCKO: Master Clock Output Enable
Default: “11” (I
0: SDTO is output by the rising edge (“↑”) of BCLK/BCLK. (default)
1: SDTO is output by the falling edge (“↓”) of BCLK/BCLK.
0: The rising edge (“↑”) of LRCK/LRCK is half clock of BCLK/BCLK before the channel change. (default)
1: The rising edge (“↑”) of LRCK/LRCK is one clock of BCLK/BCLK before the channel change.
0: Normal operation (default)
1: (L+R)/2
Default: “1111” (44.1kHz)
Default: “01” (32fs)
Default: “00” (fc=3.4Hz@fs=44.1kHz, Init Cycle=3088/fs)
0: When HPFA1-0 bits = “00”, “01”, “10”, INCA bit is invalid, when HPFA1-0 bits = “11”, ADCA Initialization
1: When HPFA1-0 bits = “00”, “01”, “10”, INCA bit is invalid, when HPFA1-0 bits = “11”, ADCA Initialization
Default: “00” (256fs)
0: Disable: MCKO pin = “L” (default)
1: Enable: Output frequency is selected by PS1-0 bits.
Cycle becomes 3088/fs.
Cycle becomes 1552/fs.
