i.MX7 EIM supported data width.

Hi community,

I have a question about i.MX7 EIM.
Would you let me know what data width is supported?
Acctually, some parts of datasheet (IMX7DCEC Rev.2) or reference manual (IMX7DRM Rev.0) say "16/32-bit supported", but other part say "x8/x16 supported".
For example, page 5 of IMX7DCEC says "16/32-bit NORFlash", and description of DSZ field in IMX7DRM (p.2562) mentions 32 bit port.
On the other hand, Table 2 and Table 37 in IMX7DCEC mention about only 8/16 bit, and chapter 9.7.1.1 of IMX7DRM also mentions only 8/16 bit.
So I'm confused which is correct.

Best Regards,

I got this answer from hardware team:

This chip only supports up to 16 bits of data on the weim interface. The 32 bit selection does not apply to this SOC.
