Function
Indirect addressing mode with the Program Counter as the source register may produce
unexpected results
Description
When using the indirect addressing mode in an instruction with the Program Counter (PC)
as the source operand, the instruction that follows immediately does not get executed.
For example in the code below, the ADD instruction does not get executed.
mov @PC, R7
add #1h, R4

Function
Wrong program trace display in the debugger while using conditional jump instructions
Description
The state storage window displays an incorrect sequence of instructions when:
1. Conditional jump instructions are used to form a software loop
AND
2. A false condition on the jump breaks out of the loop
In such cases the trace buffer incorrectly displays the first instruction of the loop as the
instruction that is executed immediately after exiting the loop.
