Description

This register disables the APPROTECT register and enables debug access to non-secure mode.

Fields

KEY

If the value of the KEY field is non-zero, and the KEY fields match on both the CPU and debugger sides, disable APPROTECT and enable debug access to non-secure mode until the next pin reset, brown-out reset, power-on reset, or watchog timer reset. After reset the debugger side register has a fixed KEY value. To enable debug access, both CTRL-AP and UICR.APPROTECT protection needs to be disabled.
