PCM4222: PCMEN pin in MBM mode

trappedinhere

Part Number: PCM4222

Tool/software:

Hello,

page 26 of the PCM4222 datasheet says the PCMEN pin should be high for MBM output mode, but page 16 of the PCM4222EVM Users Guide says the PCMEN pin should be LO in MBM output mode.

Could someone clarify the correct configuration?

thanks

Thank you for the reply. Just to be 100% clear, when PCMEN=High and MODEN=High, pins 17-->22 are MBM outputs?

That is correct. Fig 49 in the datasheet shows this setup
