Dear All,

I have a question about BCLK toggles with synchronous access in i.MX6DQ.

Refer to Page.1019 in IMX6DQRM(Rev.2).

====

The BCLK signal toggles only when burst access is executed toward the external device (BCM=1'b0 for normal mode use).

====

We assume the single read / write and burst transfer with sync access (BCM=0).

In case of single read / write, does BCLK signal toggle (output)?

Best Regards,

Keita

yes, at synchronous access BCLK signal toggles even in case of single

beat burst.
