01 Programming Model The programming model of the Cortex-M processor family is highly consistent. For example, all Cortex-M processors support R0 to R15, PSR, CONTROL, and PRIMASK. Two special registers—FAULTMASK and BASEPRI—are only supported by Cortex-M3, Cortex-M4, Cortex-M7, and Cortex-M33; the floating-point register set and FPSCR (Floating Point Status and Control Register) are used by … Read more

As we all know, ARM has renamed its products following the classic ARM11 processor to the Cortex name, dividing them into three categories: A, R, and M, aimed at serving various markets, which corresponds to the three letters of ARM’s English abbreviation. The Cortex series belongs to the ARMv7 architecture, which was the latest instruction … Read more
