Frame width of PL022 PrimeCell SPI controller

Hi all,

I'm trying to make ARM SPI controller PL022 work with Maxim MAX5134, which can be found here:

http://datasheets.maximintegrated.com/en/ds/MAX5134-MAX5137.pdf

PL022 support 16 bits width frame, while MAX5134 demand 24 bits.

From Max5134 datasheet: " If CSis driven high at any point prior to receiving 24 bits, the transmission is discarded".

PL022 will restore SSPFSSOUT after each frame that make max5134 discard data, any suggestion?

Thanks,

Steeven
