Please note that peripherals such as I2C or SPI might not work at the specified clock frequency if the selected CPU clock frequency is too low. These peripherals are clocked by the APB clock, which has a clock rate of 80 MHz for CPU clock frequencies greater than or equal to 80 MHz, but is equal to the CPU clock frequency for CPU clock frequencies less than 80 MHz. Thus, for SPI, the APB clock rate must be at least five times the SPI clock rate. For the I2C hardware implementation, the APB clock rate must be at least 40 times the I2C clock rate. For the I2C software implementation, the maximum I2C clock rate is 1/200 times the CPU clock rate. config ESP32S3_DEFAULT_CPU_FREQ_MHZ_2 bool "2 MHz" config ESP32S3_DEFAULT_CPU_FREQ_MHZ_5 bool "5 MHz" config ESP32S3_DEFAULT_CPU_FREQ_MHZ_10 bool "10 MHz" config ESP32S3_DEFAULT_CPU_FREQ_MHZ_20 bool "20 MHz" config ESP32S3_DEFAULT_CPU_FREQ_MHZ_40 bool "40 MHz" config ESP32S3_DEFAULT_CPU_FREQ_MHZ_80 bool "80 MHz" config ESP32S3_DEFAULT_CPU_FREQ_MHZ_160 bool "160 MHz" config ESP32S3_DEFAULT_CPU_FREQ_MHZ_240 bool "240 MHz" endchoice # import configuration menu entries that are common for all ESP32x SoCs rsource "Kconfig.common" endmenu endif # CPU_FAM_ESP32S3
