ls1021atwr CSU override bit

Question asked by Siles on May 11, 2016

Hi,

in the LS1021ATWR ref manual, there are 8 bits that I don't find any explain on their purpose:

CSU_SA0[4-5] CSU_SA0[6-7] CSU_SA0[8-9] and CSU_SA0[10-11]

 

They are briefly described in section 9.9.1.2 Secure Access register (p440)

 

I think the odd one is a lock for the even one, but I don't understand the purpose of the even one.

Is there some more information about these override bits ? What are they used for ?

 

Also the table CSU_SAn field descriptions just after seems to describe something else then the description from above (talking about security of masters). Is this a documentation issue or am I missing something ?

 

Best,

Vincent
