Dear all,

 

We connect an outside device to IM_CS0 of Ei.MX6.

We want to use DTACK access.

 

We want to know the timing of the access end.

We refer to the following figure.

In these figures, the timing is listed as "Sync Time".

 

What defines "Sync Time"?


IMX6DQRM.pdf(Rev2):
- 22.8.11 DTACK Mode - AXI Single Access
    Figure 22-15 / Figure 22-16 / Figure 22-17

- 22.8.12 DTACK Mode - AXI Single Write Access
    Figure 22-18

- 22.8.13 DTACK Mode - AXI Burst Access
    Figure 22-19

 

May I have advice?

 

Best Regards,
Yuuki
