-- AHB UART
--
-- Implements a serial port.
--
--------------------------------------------------------------------------------
--
-- Write registers
--
-- 00, data register receives the word to be sent to the serial port.
-- 01, control register is used to control the peripheral.
-- 02, scaler register is used to set the baud rate.
--
--------------------------------------------------------------------------------
--
-- Read registers
-- 00, data register provides the last word received by the serial port.
-- 01, status register is used to get the peripheral's state.
