ad7264 and aduc7128 connection problem

Hi ALL

I want connect ad7264 (in software mode via spi) to aduc7128. But I found problems

1. SPI module in aduc7128 work transmite only 8/16/24/32 bits . But ad7264 required 33 /47 bits.

2. If i write software spi, it made slow...

Plz help

    The SPI only can transfer Bytes, so there may be no other solution than a software SPI.

    But I did have a quick look into the AD7264 datasheet and it may be of no problem always to use 48Bit,

    6-Byte-Transfers.

    You should read the datasheet of AD7264 in detail again and may try this or ask this question in the ADC community.
