Trouble debugging with JTAG when using the WFI instruction

I know that the JTAG (SJC) controller is prone to drop off when in WFI mode because the clock source is turned off.  I have read that there is a way to keep the JTAG clock active while in WFI mode on the iMX6 but I could not find the way to do it.


I did find the SJC_GPCCR register but I don't know how to use it?
