WebSep 4, 2024 · The ARM Cortex-M specifications reserve Exception Numbers 1 - 15, inclusive, for these. NOTE: Recall that the Exception Number maps to an offset within the Vector Table. Index 0 of the Vector Table holds the reset value of the Main stack pointer. The rest of the Vector Table, starting at Index 1, holds Exception Handler pointers. WebPendSV is an interrupt-driven request for system-level service. In an OS environment, use PendSV for context switching when no other exception is active. SysTick A SysTick exception is an exception the system timer generates when it reaches zero. Software can also generate a SysTick exception. mayfield union cemetery https://casathoms.com
