According to the section 18.104.22.168 Self refresh and Frequency change entry/exit of reference manual, it shows the flow of entry and exit self-refresh mode.
However, the description doesn't say about SRX (Self Refresh Exit) command.
1. Does i.MX issue the SRX command by themself ?
2. If 1 is yes, when will it issue the command ?
Could you specify the timing in the flow of section 22.214.171.124 ?
