The monitor ROM is now allocated 320 bytes within the memory map
though not all that space is necessarily used. Functionality of the monitor
ROM is unchanged.
The EEPROM-1 and EEPROM-2 are made from a new NVM
technology. However, the bit polarity remains the same i.e.
programmed=0, erased=1.
The first major difference on the new EEPROM is that it requires a
constant time base source to ensure secure programming and erase
operations. This is done by firstly selecting which clock source is going
