Dear all.
Now I am using the cypress SPI flash memory : S70FL01GSAGBHIC10.
And I need to see current CR register configuration status especially SPI QUAD bit.
Our questions are as the following and if you have some tips or ideas for them, please give me your recommendation.
Thank you.
- I want to see current configured bit-values in CR register in memory dump information read by ROM Writer except for the use
of RDCR instruction. Is it possible to see it ? - What address of CR registor is in memory?
- CR registor is located in Sector Area of this memory?
- Is there any tools released from cypress to see the configured bits in CR registor ?
Best regards,
WonjinHan.

Hi WonjinHan,
Thank you for contacting Cypress.
The answers to your questions are as follows -
- No, it isn't.
- CR is not an addressable memory.
- Non Volatile bits of CR register are stored in a dedicated flash memory block, but a user cannot access the block directly.
- At the moment, Cypress doesn't release a tool to see flash memory in public or in the market.
Best Regards,
Apurva
