iMX93 FlexIO feature configuration

[x10]

Hi team

I'm using iMX93EVK with imx9352, and the register field FLEXIO.VERID.FEATURE = 0003h，which means supporting all functions. An iMX9302 will be used in my customer board, and I'm not sure if all flexIO functions availble just like imx9352. Please let me know the configuration of flexIO in both imx9302 and imx9332. Thanks!

Hi, NXP TechSupport

I have implemented FlexIO i8080 bus single beat transmit mode, but I found the config procedure comsumes quite lot of time, 750ns on oscilloscope, before wite pulse issued. Is it possible to enable CTRL register's FASTACC to speed up the procedure? It doesn't work for simply writing "1" to enable FASTACC bit, what's the proper way? In another hand, is it possible to speed the config procedure with higher ipg_clk? Thanks!

Hi,

Thank you for your interest in NXP Semiconductor products,

The differentiators for those parts are below, their FLEXIO number and its functionality is not affected, you may proceed in your design with the same config.

Actually, I need to emulate intel 8080 bus with FlexIO1 on iMX93EVK Linux platform. Is there  any reference code avaiable? Thanks

Hi,

Currently those demos are not implemented, you should code it on your own.
