|
||||
## Thesis
|
||||
|
||||
An ISR and a task use different APIs and different stacks. A FromISR operation
|
||||
may unblock a higher-priority task, but the task runs immediately only if the
|
||||
ISR explicitly requests a context switch.
|
||||
|
||||
## Evidence
|
||||
|
||||
The nine-record replay proves a real MEI cause, source clear before give,
|
||||
`xHigherPriorityTaskWoken=pdTRUE`, distinct ISR/waiter/stimulus stack pointers,
|
||||
and ordering `ISR → waiter → interrupted stimulus`.
