(2) Skip instructions (e.g. SNZP, INY, DEY, SZB, SEAM, SZC and RTS)
In cases when a skip instruction skips the next instruction, a breakpoint set in the skipped
instruction does not cause execution to halt. (See Program examples 6.5 and 6.6)
A breakpoint set at address POINT causes execution to halt immediately before address POINTA
in only the case of the instruction shown on the right side.
If a break with pass count is set at address POINT, the count is taken and execution is halted only
when the instruction at address POINT is executed.
