Initialization Operation
When power is applied, the INIT pin must be held LOW for the rated time to initialize the device. Initialization
sets all the CPU interface system control registers to their default values, and the outputs have the states as
described below.
Pin
DSD data outputs
8fs PCM data outputs
2fs PCM data outputs
DSBCKF, DSBCKB
F8BCK
F8WCK
F2BCK
F2LRCK
CKOUT
MONTOR
State
All “L”
All “L”
In internal 2fs output mode, all “L”
In external data output mode, output as-is in through mode
When both output modes are set, “H”
When one input mode is set, through mode output
In output mode, “H”
In output mode using FMT8WCK = “L”, “L”
In output mode using FMT8WCK = “H”, “H”
In internal data output mode, “H”
In external data output mode, external bit clock is output in through mode
In left-justified 32-bit output mode, “L”
In IIS output mode, “H”
In external data output mode, external word clock is output in through mode
MCK or EXIMCK, whichever is selected, is output in through mode
Cleared to “L”
When INIT goes “H”, the sync adjustment operation described in section “Input clock sync operation and
resynchronization” starts. Also, if DSD or PCM output is muted, the mute condition continues as-is until
released.
