6.1.6Dataflash

A 2 megabit serial dataflash on the board interfaces to the SPI. The dataflash used is a Numonyx M25PE20. The flash SPI interface is connected to the SPI interface on the EM connector. The flash chip select signal is controlled by the FLASH_CS signal (P1.4). The dataflash can be used for storing IR code libraries or Over the Air Download (OAD) images if the devices support downloading new program memory from the RF interface.
