Chapter 16 Debug Module (DBGV1)
16.3
A summary of the registers associated with the DBG sub-block is shown in
descriptions of the registers and bits are given in the subsections that follow.
16.3.1
16.3.2
This section consists of the DBG register descriptions in address order. Most of the register bits can be
written to in either BKP or DBG mode, although they may not have any effect in one of the modes.
However, the only bits in the DBG module that can be written while the debugger is armed (ARM = 1) are
