8-BIT HCS08 Microcontrollers

Chapter 7 Central Processor Unit (S08CPUV2)

7.4.5 BGND Instruction

The BGND instruction is new to the HCS08 compared to the M68HC08. BGND would not be used in

normal user programs because it forces the CPU to stop processing user instructions and enter the active

background mode. The only way to resume execution of the user program is through reset or by a host

debug system issuing a GO, TRACE1, or TAGGO serial command through the background debug

interface.

Software-based breakpoints can be set by replacing an opcode at the desired breakpoint address with the

BGND opcode. When the program reaches this breakpoint address, the CPU is forced to active

background mode rather than continuing the user program.
