When connected to RMHost, you can set and clear breakpoints and watchpoints without 
stopping your application. You can also set and clear breakpoints and watchpoints when 
your application is in a stopped state.

RMHost supports a low-intrusion code profiling mechanism. This mechanism works 
only if you enabled profiling when you built RMTarget (see the build option 

RM_OPT_GETPC

 in the building chapter of the ARM RMTarget Integration Guide). For 

details on how sample-based profiling is performed by the GetPC command, see the 
description of GetPC in the RealMonitor protocol chapter of the ARM RMTarget 
Integration Guide.

For details on code profiling using AXD, see the AXD facilities chapter of the AXD and 
armsd Debuggers Guide.

 The profiling interval specified by the debugger is ignored by RMHost. In AXD, the 
interval is specified in the Load Image dialog box.

Your application can use RealMonitor to buffer and send messages to the debugger. 
RMHost passes these messages to the Debug Comms Channel processor view in AXD. 
This feature works only if you have enabled data messaging when you built RMTarget 
(see the build option 

RM_OPT_DATALOGGING

 in the building chapter of the ARM RMTarget 

Integration Guide).

For details on the Debug Comms Channel processor view, see the AXD facilities 
chapter of the AXD and armsd Debuggers Guide. 

RMHost supports the use of the ARM semihosting interface. This support works only 
if you have enabled the SWI handler when you built RMTarget (see the build option 

RM_OPT_SEMIHOSTING

 in the building chapter of the ARM RMTarget Integration Guide).

If you are using semihosting, and you stop your application, you might receive the 
following message:

Semihosting write call interrupted (data will be lost)
