Hi sir，

The EDMA3 register “EMCR” can't be read/write that causes caused my project crashes。Do you know why the EMCR can't be access?

Hi,

Do you have anything set in EMR/EMRH?
Once a missed event is posted (by EDMA hw logic) in the event missed registers (EMR/EMRH), the bit remains set till cleared via EMCR.

EMCR is a write-only register. Attempting to read it will result in a fault.
