+title: Conexant Digicolor SoCs Watchdog timer
+
+description: |
+  The watchdog functionality in Conexant Digicolor SoCs relies on the so called
+  "Agent Communication" block. This block includes the eight programmable system
+  timer counters. The first timer (called "Timer A") is the only one that can be
+  used as watchdog.
