Chapter 3
Modes of Operation
3.1
The operating modes of the MC9S08SG8 Series are described in this chapter. Entry into each mode, exit
from each mode, and functionality while in each of the modes are described.
3.2
3.3
This is the normal operating mode for the MC9S08SG8 Series. This mode is selected upon the MCU
exiting reset if the BKGD/MS pin is high. In this mode, the CPU executes code from internal memory with
execution beginning at the address fetched from memory at 0xFFFE–0xFFFF after reset.
3.4
The active background mode functions are managed through the background debug controller (BDC) in
the HCS08 core. The BDC, together with the on-chip debug module (DBG), provide the means for
analyzing MCU operation during software development.
Active background mode is entered in any of the following ways:
After entering active background mode, the CPU is held in a suspended state waiting for serial background
commands rather than executing instructions from the user application program.

Active background mode for code development
Wait mode — CPU shuts down to conserve power; system clocks are running and full regulation
is maintained
Stop modes — System clocks are stopped and voltage regulator is in standby
— Stop3 — All internal circuits are powered for fast recovery
— Stop2 — Partial power down of internal circuits, RAM content is retained
When the BKGD/MS pin is low during POR or immediately after issuing a background debug
force reset (see
When a BACKGROUND command is received through the BKGD/MS pin
When a BGND instruction is executed
When encountering a BDC breakpoint
When encountering a DBG breakpoint
