Hi all,

In reference manual of i.MX6(IMX6DQRM.pdf) section 27.8.2,

How to work SW2ISO and SW bit in PGC_GPU_PUPSRC and PGC_GPU_PDOWNSRC

on the Wake up sequence Figure 27-5?

Which signal is it triggered the SW2ISO value counter in Figure 27-5 ?

Hello,

  The Wake up sequence is as following :

pup_req  ->  (delay of PGC_GPU_PUPSCR[SW]) -> switch_b -> delay of PGC_GPU_PUPSCR[SW2ISO] ->
-> iso

The switch_b signal, triggered with delay of  SW2ISO value counter, is not shown in Figure 27-5.

Have a great day,
Yuri
