Remarks:
--------------------------------------------------------------------------
1) : Implemnted the Hscroll register in the SHIFTER and the LINEWIDTH 
     register in the MCU.



RTC: -> Done in version 2K6B.
- Since the original real time clock RP5C15 is obsolete, there will be an approach to connect a RTC
  with I2C interface to a register bank which is compatible with the RP5C15 register bank.

CPU: -> Done in version 2K6B.
- Currently there is no MC68000 CPU available as free IP core. This will change in the next release of
  this set of configware.
