8-Bit HCS08 Central Processor Unit (CPU) • 40-MHz HCS08 CPU (central processor unit) • 20-MHz internal bus frequency • HC08 instruction set with added BGND, CALL and RTC instructions • Memory Management Unit to support paged memory. • Linear Address Pointer to allow direct page data accesses of the entire memory map
Development Support • Background debugging system • Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two more breakpoints in on-chip debug module) • On-chip in-circuit emulator (ICE) Debug module containing three comparators and nine trigger modes. Eight deep FIFO for storing change-of-flow addresses and event-only data. Supports both tag and force breakpoints.
Memory Options • Up to 128K FLASH — read/program/erase over full operating.
