AN205378 - FR, MB91460, SPI Communication to/from Serial EEPROM (for NM93CS46)
Sep 18, 2017
This application note describes how to communicate via SPI using the MB91467-USART with a serial EEPROM. In this note a NM93CS46 EEPROM from National Semiconductor is used.The described source codes were written for understanding not for code size or speed. Neither interrupts nor timers were used. Time critical coding is always done by simple flag polling or wait loop.
