MSYNC指令:
用途...當您需要load store memory都是按照順序時,要用這個指令。
它也有intrinsic function可以用,請查programming guide。

在N801-S的datasheet上有描述。

2. Memory Address Space Attributes
N801-S processor core is targeted on small systems which do not require memory management.
Therefore, N801-S processor core provides neither virtual-to-physical address translations nor
memory address space attribute definitions. The memory address space attributes are decided
based on the SoC-level implementations.
To enforce certain ordering between the loads and store memory operations, MSYNC
instructions must be inserted in the program sequence.
