WebDec 13, 2012 · Also, what's not commonly explained in SPI Flash datasheets, because it's an inherent part of the SPI protocol, which is also critical, is that for every byte one transmits on the SPI bus, one receives a byte in return. Also, one cannot receive any bytes, unless one transmits a byte.
WebOn SPI1 bus, the cache (used to fetch the data (code) in the Flash and PSRAM) should be disabled when the flash chip on the SPI0/1 is being accessed. On the other buses, the flash driver needs to disable the ISR registered by SPI Master driver, to avoid conflicts. christmas vacation 2 wikiWebSPI NAND Flash. Confidential and Proprietary 5 .
