Device Overview
1.1 Overview
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.
1.2 Features
Features have been organized to reflect:
⢠Standard features of the HCS08 Family
⢠Features of the MC9S08GBxxA/GTxxA MCU
1.2.1 Standard Features of the HCS08 Family
⢠40-MHz HCS08 CPU (central processor unit)
⢠HC08 instruction set with added BGND instruction
⢠Background debugging system (see also Chapter 15, âDevelopment Supportâ)
⢠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:
â Optional computer operating properly (COP) reset
â Low-voltage detection with reset or interrupt
â Illegal opcode detection with reset
â Illegal address detection with reset (some devices donât have illegal addresses)
