2.3 SPI Serial EEPROM/Data FLASH Memory
A 1M-bit +3.3V SPI serial EEPROM/Data FLASH Memory, Atmel AT45DB011B-SC, is
provided on the DSP56852EVM, reference
the SPI Port through a header on the DSP56852. It can be used to load program code and
data into the DSP56852's internal or external memory spaces. Jumper block JG6 is
provided to allow the user to disconnect the on-board SPI EEPROM/Data FLASH from
the SPI port and allow him to connect his own SPI port peripheral. Since the SPI port and
ISSI port are multiplexed on the DSP56852, the SPI port jumpers need to be removed to
use the ISSI port. The header details are shown in
