9.3.1.2. Writing a Platform ISR
void (*alt_isr_func) (void* isr_context)
The parameter definition of isr_context is the same as for the alt_ic_isr_register() function.
From the point of view of the HAL exception handling system, the most important function of an ISR is to clear the associated peripheral’s interrupt condition. The procedure for clearing a platform interrupt condition is specific to the peripheral.
When the ISR has finished servicing the platform interrupt, it returns to the HAL interrupt funnel that called it.
