SPI0 is used as an SPI master to access Flash and ext-SRAM SPI1 is connected to the same hardware lines as SPI0 HSPI and VSPI all have three chip select lines

use 40M clock SPI Flash can use 2 lines or 4 lines mode. If you use 2 lines mode, you can save two pad SPIHD and SPIWP for gpio. Common SPI command to configure Flash to QIO mode

miso - Also known as q, this is the input of the serial stream into the ESP32 mosi - Also known as d, this is the output of the serial stream from the ESP32 sclk - Clock signal. Each data bit is clocked out or in on the positive or negative edge of this signal quadwp - Write Protect signal. Only used for 4-bit (qio/qout) transactions. quadhd - Hold signal. Only used for 4-bit (qio/qout) transactions.

In master mode SPID = MOSI = data out SPIQ = MISO = data in
