Hi community,


Our partner have a question about i.MX6SDL EIM.

Please see chapter 22.9.1 in IMC6SDLRM (Rev.1).

I want to know what is different between the following two cases.


[Case 1]

WC: 0 (Write access burst length occurs according to BL value)

BL: 100 (Continuous burst length)

SWR: 1 (write accesses are in Synchronous mode)


[Case 2]

WC: 1 (Write access burst length is continuous)

SWR: 1 (write accesses are in Synchronous mode)


Would you let me know what is different and what defines the burst length in each case?



Best Regards,
