This used to be "see MEMORY CONTROLLER section", so I looked at the TRM to see if this was perhaps a fix for an earlier typo, but looking at the TRM (v3) I can't find a section named "ACTIVITY MONITOR". Should this be changed back to "MEMORY CONTROLLER"? Thierry

The "ACTIVITY MONITOR" is documented only in the T124/210 TRMs, the h/w modules supported by ACTMON are enumerated there. Both "ACTIVITY MONITOR" and "MEMORY CONTROLLER" could be mentioned for completeness.
