MSP430F5438A instruction cycle and clock cycle [Copy link]

One clock cycle of MSP430 = the inverse of the crystal oscillator. If the crystal oscillator is 8M, then one clock cycle is 1/8 microseconds;
one machine cycle = one clock cycle, that is, each action of 430 can complete a basic operation;
one instruction cycle = 1~6 machine cycles;
that is, it takes at most 6*1/8 microseconds to execute an instruction.

In addition, _NOP() is a single-cycle instruction, and I/O port assignment is 4 cycles.
