The STM32 family of 32-bit microcontrollers based on the Arm Cortex ® -M processor is designed to offer new degrees of freedom to MCU users. PSoC™ 6 is Infineon's newest PSoC™ MCU, built on a dual-core ARM ® Cortex ®-M architecture, delivering industry-leading ultra-low power, flexibility, and security for the IoT; Includes a high-performance ARM ® Cortex ®-M4 and a low-power ARM ® Cortex ®-M0+, industry-leading CapSense™, software-defined analog and digital peripherals, and. 6 datasheets. This new edition has been fully revised and updated to include extensive information on the ARM Cortex-M4 processor, providing a complete up-to-date guide to. Chapter 4 System Control This chapter provides a summary of the system control registers whose implementation is specific to the Cortex-M4 processor. e. Block diagram, architectural features, Micro-architectural features, Scalable instruction set, Core register set, Modes, privilege and stacks. Implementations optimized for the SIMD instruction set are available for Arm Cortex-M4, Cortex-M7, and.
