+ * @brief Registers a callback function for an interrupt.
+ * @param[in] vector Which interrupt to register a callback for.
+ * @param[in] callback Pointer to function to call when interrupt occurs.
+ * @param[in] context Pointer to the callback function's argument.
+ * @retval BSP_INT_SUCCESS Successful, callback has been registered.
+ * @retval BSP_INT_ERR_INVALID_ARG An invalid interrupt source was specified for vector.
+ * @details This function registers a callback function for an interrupt. If FIT_NO_FUNC, NULL, or any other invalid
+ * function address is passed for the callback argument then any previously registered callbacks are unregistered.
+ * If one of the interrupts that is handled by this code is triggered then the interrupt handler will query this code
+ * to see if a valid callback function is registered. If one is found then the callback function will be called.
+ * If one is not found then the interrupt handler will clear the appropriate flag(s) and exit. If the user has a
+ * callback function registered and wishes to no longer handle the interrupt then the user should call this function
+ * again with FIT_NO_FUNC as the vector parameter.
+ * @note Use of FIT_NO_FUNC is preferred over NULL since access to the address defined by FIT_NO_FUNC will cause a
+ * bus error which is easy for the user to catch. NULL typically resolves to 0 which is a valid address on RX MCUs.
