+title: Andes machine-level timer
+
+description:
+  The Andes machine-level timer device (PLMT0) provides machine-level timer
+  functionality for a set of HARTs on a RISC-V platform. It has a single
+  fixed-frequency monotonic time counter (MTIME) register and a time compare
+  register (MTIMECMP) for each HART connected to the PLMT0. A timer interrupt is
+  generated if MTIME >= MTIMECMP.
