In many cases, developers can use the Cortex-M processor's unique features to optimize for product cost or energy appetite while maintaining, or even improving, its performance. For example, the Cortex-M core has native serial I/O capabilities that can be Silicon Labs Rev 1.0 2 used to ...
This includes the CPU programmers model, the processor memory map and busses, power management, and fault conditions. We also examine the system control block registers used to configure operation of the Cortex-M processor. Once the basic Cortex processor architecture is understood, we take a ...
M可以看作是R的阉割版，只支持Thumb指令集而不支持ARM指令集，也不支持大端序、双精度等特性。M和R的...
