Regarding CTRL-AP erase all operation

[KPA]

Hi team,


According to this statement, it indicates that access port protection can be deactivated by modifying the TAMPC.PROTECT registers, which can be achieved by executing the CTRL-AP erase all operation.
Is it feasible to disable the access port protection without performing the CTRL-AP.Erase All operation, assuming that my flash memory is currently empty?

Therefore, is there any available source code that encompasses the following details, as outlined in the abstract from the nRF54L Series Production Programming application manual.

Hi, 

If the device has access port protection enabled and is not erase protected, you can disable access port protection by using a Control Access Port (CTRL-AP) erase all operation. See Disabling APPROTECT.

This statement is clear. My request is as follows,
Is there any source code available that I can refer, to execute the erase all operation using CTRL-AP?

Unfortunately, no, but you can refer to Disabling APPROTECT.
