+-- Created:         January 2019
+-- Author(s):       Philip Smart
+-- Description:     An extension of the simplistic UART Tx, still fixed at 8N1 with configurable baud rate
+--                  but adding a debug serialisaztion FSM for output of ZPU runtime data.
+-- Credits:         Originally using the simplistic UART as a guide, which was written by the following
+--                  authors:-
+--                  Philippe Carton, philippe.carton2 libertysurf.fr

+-- History:         January 2019  - Initial module written using the simplistic UART as a guide but
+--                                  adding cache and debug serialisation FSM.
