3.5.1 Master/Slave Mode
Master (the MB86391 outputs ACLK and ALRCK) and slave (input of ACLK and ALRCK from the
audio A/D converter to the MB86391) modes can be switched.
3.5.2 Input Formats
Setting each of the following parameters allows compatibility with various input formats:
(1) MSB first/LSB first of data
(2) Packing ALRCK with data (left/right packing))
(3) ALRCK polarity (‘H’=Lch, ’L’=Rch / ‘L’=Lch ’H’=Rch)
(4) Phase relationship between ALRCK and data (compatible with I²S interface)
The phase relationship between ALRCK and ACLK is adjustable by 256 fs in master mode.
