Breakpt Read

Breakpt Read
The Breakpt Read command sets a read breakpoint. The read breakpoint halts
program execution each time the target program attempts to read data from
the specified memory location (< addr> ) or range (< addr> ..< addr> ).
The Breakpt Read command behaves just like the Breakpt Access command.
See Also Breakpt Access
Examples
To set a breakpoint on reads from variable 'system_running':
Breakpt Read &system_running
To set a read breakpoint starting at the address of variable 'current_temp' and
ending 8 bytes after the address of 'current_temp':
Breakpt Read &current_temp..+8
To stop program execution when the value of variable system_running is read
as TRUE:
Breakpt Read &system_running; when (system_running==1)
