WebCache: the prefetch buffer is a simple type of cache. ... It is now indexed by search engines. So it may help folks use the STM32 in particular, and MCUs in general in more informed, imaginative, useful and low-power ways :-) You may have helped the human race reduce the heating effect of our technology a little bit. Kudos to you. \$\endgroup\$ WebJul 2, 2024 · fiq: NMI in Traveo. For example, to catch a prefetch abort, use the following command: target set catch_prefetch on. The advantage of stopping directly on abort occurrence and not putting a breakpoint anywhere in the exception handler is that no CPU registers are modified by the exception handler code itself.
