Dual Core – Modes of Operation DPM LSM Decoupled Parallel Mode Lock. Step Mode 1 x performance ► MCU mode which allows SIL 3/ASIL-D with minimal software overhead ► Formal check of outputs for replicated IP modules ► Checker (RC) guarantee detection of noncommon cause faults when redundant channels are merged ► ► Up to 2 x performance ► MCU mode which allows SIL 3/ASIL-D with algorithm diversity ► CPU cores and subsystems run independently ► Checker units (RC) are disabled in this mode § Symmetric dual-core device § Device concept supports static configuration of the operating mode during Reset § Selection between the two modes is done by programming a user option bit stored in the shadow block of the flash array Freescale™ and the Freescale logo are trademarks of Freescale Semiconductor, Inc.
