Features:
• 8-Bit HCS08 Central Processor Unit (CPU)
   – Up to 40 MHz CPU at 2.7 V to 5.5 V across temperature range of –40 °C to 85 °C
   – HC08 instruction set with added BGND instruction
   – Support for up to 32 interrupt/reset sources
• On-Chip Memory
   – Up to 16 KB flash read/program/erase over full operating voltage and temperature
   – Up to 1024-byte random-access memory (RAM)
   – Security circuitry to prevent unauthorized access to RAM and flash contents
• Power-Saving Modes
   – Two low power stop modes; reduced power wait mode
   – Allows clocks to remain enabled to specific peripherals in stop3 mode
• Clock Source Options
   – Oscillator (XOSC) — Loop-control Pierce oscillator; crystal or ceramic resonator range of 31.25 kHz to 39.0625 kHz or 1 MHz to 16 MHz
   – Internal Clock Source (ICS) — Internal clock source module containing a frequency-locked-loop (FLL) controlled by internal or external reference; precision trimming of internal reference allows 0.2% resolution and 2% deviation over temperature and voltage; supporting bus frequencies up to 20 MHz
• System Protection
   – Watchdog computer operating properly (COP) reset with option to run from dedicated 1 kHz internal clock source or bus clock
   – Low-voltage detection with reset or interrupt; selectable trip points
   – Illegal opcode detection with reset
   – Illegal address detection with reset
   – Flash block protection
• Development Support
   – Single-wire background debug interface
   – Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two more breakpoints)
   – On-chip in-circuit emulator (ICE) debug module containing two comparators and nine trigger modes
