Field FUN_DRV reader - 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.
Field FUN_DRV writer - 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.
Field FUN_WPD reader - 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.
Field FUN_WPD writer - 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.
Field FUN_WPU reader - 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.
Field FUN_WPU writer - 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.
