We would like to use the I2C EEPROM option to boot the FX3. I believe our code would fit in 1 24LC1025 Microchip EEPROM but I will use 2 just in case. Now if I am only using 2 do I place them in the 0x00000-0x1FFFF and 0x20000-0x2FFFF range tying A1 to a 0 and A0 to a 0 and 1 respectively as per page 16 of the AN76405 APP Note.
Or do I place the 2 EEPROMs in the upper range 0x40000-0x5FFFF and 0x60000-0x7FFFF?
You need to place them in lower range -0x00000-0x1FFFF and 0x20000-0x2FFFF tying A1 to a 0 and A0 to a 0 and 1 respectively as per page 16 of the AN76405 APP Note.
