The condition of DAI_PBEN register (About ADSP-21569)
Hello.
Could you tell me the condition of DAI_PBEN register?
Which is correct high or low when I want to set the terminal as Hi-z ( for use as input).
And coule you tell in which document described detail about this?
(Sorry, I can't find it.)

Hi Masa Hibino,
When a pin buffer enable (DAIn_PBENxx_I) is set (=1), the signal present at the corresponding pin buffer input (DAIn_PBxx_I) is driven off-chip as an output.
When a pin buffer enable is cleared (=0), the signal present at the corresponding pin buffer input is ignored. The pin enable control registers activate the drive buffer for each of the DAI pins. When the pins are not enabled (driven), they can be used as inputs.
We would suggest you to refer "I/O Pin Buffers" (Page No:919/2331). The link for the ADSP-2156x Hardware Reference Manual is given below.
