increment this inner loop counter by 1 each time but the source line with the breakpoint will never be reached, until the loop
temrinating condition is satisfied.
If we examine the actual opcodes being stepped, we can see the PC has stopped at the opcode after the non-delay branch
instruction, as previously explained (i.e. the data access break bit is enabled).

ISASSEMBLY VIEW OF CODE
The solution to this problem is to bypass the BT/BF UBC issue and set the beakpoint at the actual opcode (as opposed to
the source line consisting of the set of opcodes).

REAKPOINT
OLUTION IN DISASSEMBLY
In Figure 7-4 the breakpoint has been set at the opcode MOV.W R5, @R4 (the line that actually sets the LED bits into the
appropriate register). If we perform a Debug | Run, we are no longer trying to break immediately after the non-delay branch,
