Hi community,


I have a question about i.MX6DQ eCSPI.

Please see chapter and chapter 21.7.3 BUST_LENGTH description in IMX6DQRM (Rev.3), these describe eCSPI behavior when SS_CTL is cleared in slave mode.

On the other hand, chapter 21.4.2 says "Slave mode only supports the case when SSCTL (SSB_CTRL[x] bit) is cleared.", and chapter 21.7.4 SS_CTL description says SS_CTL=0 is reserved in slave mode.


Which is correct?

Is SS_CTL=0b in slave mode supported? or not supported?
