Hello Freescale people,


I would like to know the implementation of SPSEL bit (bit[1]) value of CONTROL register of KInetis of which CPU is Cortex-M0+.

According to my experiment, SPSEL bit was fixed to 0 by KL25Z. This means the stack pointer would be always MSP even in the thread mode, doesn't it?

How about the other Kinetis MCUs?


Best regards,
