About movement of DDRMC after having returned from LPSTOP3

Hi,

 

After LPSTOP3 exit, I set DDRMC again.

And I set it with DDRMC_CR00=0x0501.

Then there is the case that DDRMC_CR80[bit8] is not set.

 

I set it in CCM_CCSR=01, and outbreak frequency increases when I enter LPSTOP3.

 

Q1)

When DDRMC_CR80[bit8] is not set, what will be regarded as a factor?


Best regards,

soichi
