Memory Attribution Specifiers

Memory Attribution Specifiers are address extensions for explicit secure or non-secure accesses in debug commands. µVision provides predefined memory attribution specifiers. Memory attribution specifiers are separated by a colon (:) from the memory address.

These specifiers are available for all debug commands and features (especially constants and program variables) that represent a target memory address or require a target memory access to resolve an expression:

The table below shows the memory attribution specifiers and their availability for different Arm Cortex-M architectures.

Specifier Armv6-M Armv7-M Armv8-M Description
No specifier available available available Debugger decides on the access (usually secure for Armv8-M).
S:     available Secure debug access on debug access port (DAP).
NS:     available Non-secure debug access on debug access port (DAP).

Memory attribution specifiers can be used in the following commands and debug functions:

  • SAVE
  • D (Display)
  • WS (WatchSet)
  • E (Enter)
  • memset() function
  • T (Step)
  • P (Step Over)
  • G (Go)
  • LA (Logic Analyzer)
  • TR, TS, TH, TDP, TAP (Tracepoint Commands)
  • BS, BL, BA (Breakpoint Commands)
  • SBC (Software Breakpoint Configuration)
  • EVAL
