OPT8241-CDK-EVM: FX2 Mode in OPT8241-CDK-EVM

Part Number: OPT8241-CDK-EVM

Hi there,

I am having a hard time finding out what mode the FX2 on the OPT8241-CDK-EVM should be in? I looked at the User Guide and can't find anything. I cannot seem to find whether it is to operate as GPIF or slave FIFO mode 8 bits or 16 bits. Are there any hardware pins that can control this?

Also, another question is does OPT9221 support 4 byte parallel mode?

Thanks.
