Pin detail information on ADAU1452
Hello All,
I have two questions.
For the hardware development stage, I would like you to respond me by February 6.
Question 1:
Is there any change or update information related to other past QA?

[ADAU145xDefaultPinStates.xlsx]
Question 2:
When / RESET = "L", when there is a signal input to a certain input signal pin, is the output signal pin related to that pin react and the state changes? ("H" → "L" or inverted)
For example, SDATA_OUT 0 is output when clock input is made to BCLK_OUT 0 and LRCLK_OUT 0 during / RESET = "L", etc.

Hello HTCV3,
I have not updated the spreadsheet in the link. On the post another user offered some other information which I have not verified or confirmed.
In your example, the BCLK and LRCLK pins are bi-directional and as such they will tri-state as soon as the reset is pulled low so there is no way the serial data out will be clocked.
