//! \brief Registers a function as an interrupt handler in the dynamic vector table.
//!
//! \note Only use this function if you want to use the dynamic vector table (in SRAM)!
//!
//! This function writes a function pointer to the dynamic interrupt vector table
//! in SRAM to register the function as an interrupt handler (ISR). When the corresponding
//! interrupt occurs, and it has been enabled (see \ref IntEnable()), the function
//! pointer is fetched from the dynamic vector table, and the System CPU will
//! execute the interrupt handler.
//!
//! \note The first call to this function (directly or indirectly via a peripheral
//! driver interrupt register function) copies the interrupt vector table from
//! Flash to SRAM. NVIC uses the static vector table (in Flash) until this function
//! is called.
//!
