With 32-bit reading all Ok.

But with writing the every second pulse ALE is missed.

Explain please to me how correctly adjust EMI-registers to solve this problem, if it possible at all.

Scheme and timing diagram is attached.

The problem is solved.

The fact was that I incorrectly changed the condition of register EMI_BCRx

Instead of 0x00303010 I wrote down 0x00003010 and it gave fatal consequences. ;)
