The MC68331 is a highly-integrated 32 bit microcontroller that combines high-performance data manipulation capabilities with powerful peripheral subsystems.This MCU is built up from standard modules that interface through a common intermodule bus (IMB). The MCU incorporates a 32 bit CPU (CPU32), a system integration module (SIM), a general purpose timer (GPT) and a queued serial module (QSM).Modular ArchitectureCentral Processing Unit (CPU32)Upward Object Code CompatibleNew Instructions for controller Applications32 Bit ArchirectureVirtual Memory ImplementationLoop Mode of Insruction ExecutionTable Lookup and Interpolate InstructionImproved Exception Handling for Controller ApplicationsTrace on change of flowHardware breakpoint signal, Background Debugging Mode (BDM)Fully static operation
