Espruino on P8 smartwatch - ST7789 display driver in Inline C

not only chip select pins, also whole spi interface, there is new define constant merged recently here https://github.com/espruino/Espruino/pull/1943 so that you can pull flash cs high and it will restart reading. However you must also disable hw spi to release clk,mosi pins as the spi flash code uses software spi and needs it as gpios. or the spi flash code would need to use same hardware spi too but that may cause other issues
