SYStem.Option DACR Debugger ignores DACR access permission settings
Default: OFF.
Derivatives having a Domain Access Control Registers (DACR) do not allow the debugger to access
memory if the location does not have the appropriate access permission. If this option is activated, the
debugger temporarily modifies the access permission to get access to any memory location.
SYStem.Option DAPNOIRCHECK No DAP instruction register check
Default: OFF.
Bug fix for derivatives which do not return the correct pattern on a DAP (ARM CoreSight Debug Access Port)
instruction register (IR) scan. When activated the returned pattern will not be checked by the debugger.
SYStem.Option DAPREMAP Rearrange DAP memory map
The Debug Access Port (DAP) can be used for memory access during runtime. If the mapping on the DAP is
different than the processor view this re-mapping command can be used. Up to 16 <address_range>/
<address> pairs are possible.
SYStem.Option DBGACK DBGACK active on debugger memory accesses
Default: ON.
If this option is on the DBGACK signal remains active during memory accesses in debug mode. If the
DBGACK signal is used to freeze timers or to disable other peripherals it is strictly recommended to enable
this option.
