2.3 SPI EEPROM Memory
A 1Mbit, +3.3V, SPI, serial EEPROM Memory, Atmel AT45DB011-SC, is provided on
the 56F826EVM; reference
through a header on the 56F826. It can be used to load program code and data into the
56F826's internal or external memory spaces. A jumper block, JG7, is provided, which
allows the user to disconnect the on-board SPI EEPROM from the SPI port and to connect
his own SPI port peripheral. The header details are shown in
56F826
