Starterware/AM3352: I2S bit mask

Kim Dongjin

Part Number: AM3352

Tool/software: Starterware

I receive audio data from bluetooth device in I2S 24 word length MSB bit format.

In this case I confuse bit mask value. I do not know which is correct.

b1111111111111111111111111111111 (0xFFFFFFFF)

b00000000111111111111111111111111 (0xFFFFFF)

b00000011111111111111111111111100 (0x3FFFFFC) empty the first bit

thank you

Hi,
What software is this? Which version?

I am using linux kernel 4.4.32

I know "davinci_config_channel_size()" function configure bit format and mask values.

But I confuse how to configure them in this case (different size between slot size and word size)

thank you
