configuration registers overlay the UART registers and are
selected by paging.
The EEPROM can also be used to redefine the reset
values of all register areas to tailor the device to the end
users requirements if the default values do not meet the
specific requirements of the manufacturer. This re-
programming of the device can also be performed for the
CIS area, allowing the manufacturer to modify resources
required, or Manufacturer ID values for example. As an

additional enhancement, the EEPROM can be used to pre-
program the UART, allowing pre-configuration, without
requiring device driver changes. This allows the enhanced
features of the integrated UART to be in place prior to
handover to any generic device drivers.
Note that a default set of tuples is provided for both
operating modes thus allowing for a single chip solution in
either mode. ‘Generic’ normal mode can also be
implemented through EEPROM configuration.
