PIC microcontroller embedded eight function, most other NXP without the limit, for example, why? Please help solve, thank you

CodePudding user response:

Should be limited by the size of the stack, stack overflow is finished

CodePudding user response:

If determined by the hardware, the hardware of the POP, PUSH instructions relating to the stack is a fixed position, will have the most number of multilayer limit, a lot of low cost single chip microcomputer to do so.
And some of the stack location can be changed, such as 51 SP pointer, although it is not recommended, but it can be modified, such as long as enough RAM, how many layers are no problem
