Hello,

I have 2 questions.

1. Can I transfer Just one frame per block?

2, I can't seem to find the maximum Bclk or Wclk frequencies:( (I looked. I promise)?

Thank you,

Ken

Hi,

You should find all info on I2S here (see Ch.22):

Thank you Zahid,

I'm looking for limits that don't seem to be listed in chapter twenty two. Timing specifications such as min and max frequency and pulse width for WCLK and and BCLK would be an example. The delay in ns from BCLK to ADx valid would be another example. If you have a link to a timing diagram that would be very helpful??

Thanks again,
Ken:)

Hi Ken,

MCLK should be fine up to 24MHz, and BCLK up to 12MHz. It is not limited by the I2S module, but rather the IOs. They share IOs with SPI module which is limited to 12MHz as Master in the datasheet, but which have been used @20MHz.
