WebDec 13, 2012 · The following information is available from the timing diagrams in datasheets of SPI Flashes, but sometimes folks overlook bits. All commands and data are issued to the SPI flash using the SPI bus. The sequence to read a SPI Flash is: 1) Start with CS_ high. 2) Bring CS_ low. 3) Issue "Read" op code to SPI Flash. WebFlash_Write_Data will write data to the given memory location. It will calculate the start sector number based on the address given in the parameter then, the sector address of …
