Device Overview
1.1
The MC9S08GBxxA/GTxxA are members of the low-cost, high-performance HCS08 Family of 8-bit
microcontroller units (MCUs). All MCUs in the family use the enhanced HCS08 core and are available
with a variety of modules, memory sizes, memory types, and package types.

Features of the MC9S08GBxxA/GTxxA MCU
40-MHz HCS08 CPU (central processor unit)
HC08 instruction set with added BGND instruction
Background debugging system (see also
Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two
more breakpoints in on-chip debug module)
Debug module containing two comparators and nine trigger modes. Eight deep FIFO for storing
change-of-flow addresses and event-only data. Debug module supports both tag and force
breakpoints.
Support for up to 32 interrupt/reset sources
Power-saving modes: wait plus three stops
System protection features:
— Optional computer operating properly (COP) reset
— Low-voltage detection with reset or interrupt
— Illegal opcode detection with reset
— Illegal address detection with reset (some devices don’t have illegal addresses)
