Fields

MCU_OE

Output enable of the pad in sleep mode. 1: enable output; 0: disable output.
SLP_SEL

Sleep mode selection of this pad. Set to 1 to put the pad in sleep mode.
MCU_WPD

Pull-down enable of the pad during sleep mode. 1: internal pull-down enabled; 0: internal pull-down disabled.
MCU_WPU

Pull-up enable of the pad during sleep mode. 1: internal pull-up enabled; 0: internal pull-up disabled.
MCU_IE

Input enable of the pad during sleep mode. 1: input enabled; 0: input disabled.
MCU_DRV

Select the drive strength of the pad during sleep mode. A higher value corresponds with a higher strength.
FUN_WPD

Pull-down enable of the pad. 1: internal pull-down enabled, 0: internal pull-down disabled. GPIO pins 34-39 are input-only. These pins do not feature an output driver or internal pull- up/pull-down circuitry, therefore, their FUN_WPD is always 0.
FUN_WPU

Pull-up enable of the pad. 1: internal pull-up enabled; 0: internal pull-up disabled. GPIO pins 34-39 are input-only. These pins do not feature an output driver or internal pull- up/pull- down circuitry, therefore, their FUN_WPU is always 0.
FUN_IE

Input enable of the pad. 1: input enabled; 0: input disabled.
FUN_DRV

Select the drive strength of the pad. A higher value corresponds with a higher strength. For GPIO34-39, FUN_DRV is always 0. For detailed drive strength, please see note 8 in Table ”Notes on ESP32 Pin Lists”, in ESP32 Datasheet.
MCU_SEL

Select the IO_MUX function for this signal. 0 selects Function 0, 1 selects Function 1, etc.
