Note: If your ISR is located in a vector table, the HAL does not provide funnel code. In this case, your
code must manage the stack pointer, as well as all other funnel code functions.
For more information about implementing a separate hardware interrupt stack, refer to AN595: Vectored
Interrupt Controller Applications and Usage.
