Can I open automatically a specific section in the peripheral file with TRACE32 command ?
Ref: 0585

Yes, You need to specify the path to open this section with the command PER (sections and subsections are delimited by ",")
PER , "Nested Vectored Interrupt Controller,Interrupt Enable Registers"

Is it possible to use TABs between quotes instead of whitespaces in a PER file?
Ref: 0584

Example: textline "<tab><tab>" instead of textline "<whitespaces...>"

The answer is no. No error will be generated but the PER window will display special characters instead of the tabs.

Why do I get an error when I try to read a peripheral register?
Ref: 0536

Usually, this happens if the module is accessed before its clock has been enabled. Accessing the peripheral registers generally results in such case in bus errors (questions marks displayed instead of value). It can even cause is some cases a processor crash since the access creates a bus stall which then blocks the memory access until a new reset is asserted. Before accessing a peripheral module, it is thus important that its clock is already enabled.
