WebCRL is used to set type/and or speed of pins 0-7 of the port. Accessed as a 32 bit word, with 4 bits representing the state of each pin. Out of these 4 bits, the low 2 bits are MODE, and high 2 bits are CNF. The 4 bits for each pin can be set to: 0b0011 (binary) or 0x3 (HEX) - Corresponds to setting pin as output, same as pinMode () Webfunc – The function number of the peripheral pin to output pin. One of the FUNC_X_* of specified pin (X) in soc/io_mux_reg.h. oen_inv – True if the output enable needs to be inverted, otherwise False. esp_err_t gpio_sleep_sel_en (gpio_num_t gpio_num) Enable SLP_SEL to change GPIO status automantically in lightsleep.
