This program accesses a SPI EEPROM USing polled mode access. The F12x MCU is configured in 4-wire Single Master Mode, and the EEPROM is the only slave device connected to the SPI bus. The read/write operations are tailored to access a Microchip 4 kB EEPROM
All programs were tested USing a breadboard containing a DS80C320,
32K Program memory, 32K Data memory, two 8-segment bar graph
LEDs/drivers, and an 11.0592 MHz crystal. The four 8-segment bar graph
LEDs/drivers were connected to ports 1, and 3 to display their
pins states.
