STM32F130 and Timer 8

STM32F130 contains two adwanced timers - 1 and 8. But Keil's 
STM32_Init.c and its Configuration Wizard knows Timer 1 only. After 
"manual" programming it works but I cannot find its interrupts. How can 
I add interrupt subroutine? NVIC is initialized:
NVIC->ISER[1]  = (1 << (TIM8_UP_IRQChannel & 0x1F));
