> The Cortex-M allows changing > the vector table after > initialization This is actually an optional feature, and not all Cortex-M parts implement it. All Cortex-M0 do not, some Cortex-M0+ also do not. Most Cortex-M3+ do. But Author keeps saying "Cortex-M0" which do not. Also, the part she is talking about is a Cortex-M0+ not a Cortex-M0 (big difference)
