+description: |
+  Advanced High-performance Bus Controller (AHBC) supports plenty of mechanisms
+  including a priority arbiter, an address decoder and a data multiplexer
+  to control the overall operations of Advanced Highperformance
+  Bus (AHB). AHB is the main system bus for ARM CPU to communicate with the
+  related peripherals.
