Definitions3.3Strapping PinsESP32-S2has three strapping pins:GPIO0,GPIO45,GPIO46.The pin-pin mapping between ESP32-S2and the module is as follows,which can be seen in Chapter5Schematics:•GPIO0=IO0•GPIO45=IO45•GPIO46=IO46Software can read the values of corresponding bits from register”GPIO_STRAPPING”.During the chip’s system reset(power-on-reset,RTC watchdog reset,brownout reset,analog super watchdog reset,and crystal clock glitch detection reset),the latches of the strapping pins sample the voltage level as strapping bits of”0”or”1”,and hold these bits until the chip is powered down or shut down.IO0,IO45and IO46are connected to the internal pull-up/pull-down.If they are unconnected or the connected external circuit is high-impedance,the internal weak pull-up/pull-down will determine the default input level of these strapping pins.To change the strapping bit values,users can apply the external pull-down/pull-up resistances,or use the host MCU’s GPIOs to control the voltage level of these pins when powering on ESP32-S2.After reset,the strapping pins work as normal-function pins.Refer to Table3for a detailed boot-mode configuration of the strapping pins.Table3:Strapping Pins4.Electrical Characteristics4.1Absolute Maximum RatingsTable4:Absolute Maximum Ratings4.2Recommended Operating ConditionsTable5:Recommended Operating
