WebIf the hardware interface has the ready busy pin of the NAND chip connected to a GPIO or other accessible I/O pin, this function is used to read back the state of the pin. The function has no arguments and should return 0, if the device is busy (R/B pin is low) and 1, if the device is ready (R/B pin is high). WebJan 29, 2024 · 1 Answer. Sorted by: 2.

"WebSPI NAND Flash supports Quad SPI operation when using the x4 and Quad IO commands. These commands allow data to be transferred to or from the device at four times the rate of the standard SPI. When using the Quad SPI command the SI and SO pins become bidirectional I/O pins: SIO0 and SIO1, and WP# and HOLD# pins become SIO2 and SIO3. " - Spi nand read oob error
