Software Breakpoint
none | This instruction does not have any operands |
LSW: 0000 0000 0000 0000
MSW: 0111 1111 0011 0000
The instruction at which a software breakpoint is placed is replaced by the MDEBUGSTOP1 instruction. The instruction halts execution once the instruction reaches the D2 phase in the pipeline; at that point, the subsequent instructions that were fetched, after the halt, are flushed from the pipeline. The replace instruction is re-fetched after this and execution continues normally (either in run or step mode).
See Section 8.4.3 for a detailed explanation of the operation.
The MDEBUGSTOP1 instruction cannot be placed 3 instructions before or after a MBCNDD, MCCNDD, or MRCNDD instruction.
This instruction does not modify flags in the MSTF register.
Flag | TF | ZF | NF | LUF | LVF |

Modified | No | No | No | No | No |
This is a single-cycle instruction.
