BREAK

On-chip Debug system breakpoint instruction.

None

PC = PC + 1

1001010110011000

Description

The BREAK instruction is used by the On-chip Debug system and not used by the application software. When the BREAK instruction is executed, the AVR CPU is set in the Stopped state. This gives the On-chip Debugger access to internal resources.

If the device is locked, or the on-chip debug system is not enabled, the CPU will treat the BREAK instruction as a NOP and will not enter the Stopped state.

This instruction is not available on all devices. Refer to Appendix A.
