I can not restore access to QUAD SPI memory (ASMI Parallel II Intel FPGA IP )

Hello Support!

I use ASMI Parallel II Intel FPGA IP for access to MT25QU512.

This memory connected to Cyclone 10 GX by "AS config" sheme.

Before doing the following, i could write and read memory by avalon and jtag interfaces.

I performed the following steps on the AVL bus:

  1. read from RD_NON_VOLATILE_CONF_REG 0xafee
  2. write to WR_NON_VOLATILE_CONF_REG 0xafe2

After these actions, I no longer access to MT25QU512 by avalon and jtag .

I understand that I was writing incorrect values to memory.

How can I regain access to memory?

I have attached log from the programmer when writing the jic file
