13.4. CP14 registers reset

The CP14 debug registers are all reset by the ARM1136JF-S processor power-on reset signal, nPORESETIN, see Power-on reset.

This ensures that a vector catch set on the reset vector is taken when nRESETIN is deasserted. It also ensure that the DBGTAP debugger can be connected when the processor is running without clearing CP14 debug setting, because DBGnTRST does not reset these registers.
