I want to read the ECRP protection level of an LPC54628. The user manual UM10912 section 49.6.4 says the ISP-AP is active no matter what ECRP level is set. Table 1078 describes the ISP-AP command "Query ECRP Level" which presumably returns the relevant bits I need.
Can anyone describe how to execute this ISP-AP command using a J-Link or Link-2 debugger and how the data is returned?
Thanks.
