(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 skippedinstruction 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.
