Where are the SysTick registers in CSS for LM4F?

I am debugging a LM4F app in CSS.  My SysTick interrupt is no longer hitting.  I am trying to find the peripheral's registers, but cannot.  Can anyone point me to where they are in the list of registers.  I may be blind, but I cannot find CTCTRL.

    John,

    I don't know what CTCRL is.  I'm guessing it's the ARM name for one of the SysTick control or status registers.  If so, I think you're looking for the NVIC_ST_xxx registers defined in inc/hw_nvic.h; e.g., the first register is the control and status register (NVIC_ST_CTRL) at 0xE000E010.
