Subsystem
The TrustZone watchdog (TZ WDOG) timer module protects against
TrustZone starvation by providing a method of escaping normal mode and
forcing a switch to the TZ mode. TZ starvation is a situation where the
normal OS prevents switching to the TZ mode. This situation should be
avoided, as it can compromise the system’s security. Once the TZ WDOG
module is activated, it must be serviced by TZ software on a periodic basis.
If servicing does not take place, the timer times out. Upon a time-out, the
TZ WDOG asserts a TZ mapped interrupt that forces switching to the TZ
mode. If it is still not served, the TZ WDOG asserts a security violation
signal to the CSU. The TZ WDOG module cannot be programmed or
deactivated by a normal mode SW.
