(2) Skip instructions (e.g. SNZP, INY, DEY, SZB, SEAM, SZC and RTS instructions)

When a skip instruction skips the next instruction, a breakpoint set in the skipped instruction does

not break. (See Program examples 5.5 and 5.6)

Program example 5.5

POINT: TABP POINT: TABP

POINTA: TAM 0 POINTA: TAM 0

• •

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.

RC ; Skip instructions

INY

POINT: TABP

LA 0

•

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.
