If it's of any interest, the version 3.2 of the library implements it like this,

static __INLINE void NVIC_SystemReset(void) {   SCB->AIRCR  = ((0x5FA << SCB_AIRCR_VECTKEY_Pos) |   (SCB->AIRCR & SCB_AIRCR_PRIGROUP_Msk)           |   SCB_AIRCR_SYSRESETREQ_Msk); /* Keep priority group unchanged */   __DSB();                    /* Ensure completion of memory access */                while(1);                   /* wait until reset */ } John F.

The softreset has a curious feature:

In my tests the softreset is about 150 times slower than a hardreset! The resethandler did only the respective reset. Time measured between two consecutive resets: - softreset ~760µs - hardreset ~5µs
