1. The storage structure of msp430 adopts the von Eman structure, that is, RAM and Flash are uniformly addressed in the same addressing space, without distinction between code space and data space.
2. Flash is stored in segments as the basic structure. Generally, it is divided into three parts:
Flash main storage area: used to store program code, divided into 4 sectors, each sector is divided into 128 segments, each segment size is 64 * 1024 / 128 = 512B. Flash controller can write to Flash controller in bit, byte, or word format. But the smallest erase unit of the controller is segment.
BSL storage area: It is the boot loader memory of the memory, which can be used to store the boot loader program. It is divided into 4 segments, each with 512B. Each segment can be erased separately.
Information storage area: mainly used to store data that needs to be permanently saved after power failure, divided into 4 segments, each 128B. Each segment can be erased and written separately.
