depends on ESPTOOLPY_FLASHMODE_DIO || ESPTOOLPY_FLASHMODE_DOUT
range 0 33
default 7
help
This value is ignored unless flash mode is set to DIO or DOUT and the SPI flash pins have been
overriden by setting the eFuses SPI_PAD_CONFIG_xxx.
When this is the case, the eFuse config only defines 3 of the 4 Quad I/O data pins. The WP pin (aka
ESP32 pin "SD_DATA_3" or SPI flash pin "IO2") is not specified in eFuse. And the psram only has QPI
mode, the WP pin is necessary, so we need to configure this value here.
When flash mode is set to QIO or QOUT, the PSRAM WP pin will be set as the value configured in
bootloader.
For ESP32-PICO chip, the default value of this config should be 7.
