This command sets a watchpoint for a data symbol. The debugger stops the target when the memory at the specified address is read.
Watchpoints are only supported on scalar values.
Some targets do not support watchpoints. Currently you can only use watchpoint commands on a hardware target using a RealView® ICE unit.
The address of the instruction that triggers the watchpoint might not be the address shown in the PC register. This is because of pipelining effects.
