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
No bright ideas from me sorry - the two requirements seem incompatible and given SPI is self-managing in terms of frames, so I'm not sure there is an easy way to solve this one sort of sticking an extra hardware block in the middle to translate the two protocols.
