satcat5::sam::HandlerSAMV71 Class Reference

Detailed Description

Interrupt handler interface for the Microchip SAM V71.

This class is needed to apply NVIC_USER_IRQ_OFFSET when creating SAMV71 interrupt handlers. SatCat does not allow negative IRQ nums, and the SAMV71 has a few Ex: SysTick_IRQn. So when creating the Handlers NVIC_USER_IRQ_OFFSET is applied to bring this number to be positive. The controller uses this value to revert the offset when attempting to set the ISR vector for the given interrupt.
