6.1 Operation Sequences

Following is the SW-DP sequence:
  1. Perform a line Reset (refer to Device Reset).
  2. Enter into the SW-DP mode by following initialization (see SW-DP section).

Once access to SW-DP is enabled, the debugger can access the MEM-AP.

Following is the MEM-AP sequence:

  1. Get Device ID.
  2. Get code protection and secure device status.
  3. Read memory (each area of memory (SRAM, peripheral registers, Flash, eFuse) requires programming operations to access).
  4. Write memory (each area of memory (SRAM, peripheral registers, Flash, eFuse) requires programming operations to access).
  5. Read Debug Halting Control and Status Register (DHCRS).
