- Field - FUN_DRVreader - 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_DRVwriter - 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_IEreader - Input enable of the pad. 1: input enabled; 0: input disabled.
 
- Field - FUN_IEwriter - Input enable of the pad. 1: input enabled; 0: input disabled.
 
- Field - FUN_WPDreader - 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_WPDwriter - 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_WPUreader - 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_WPUwriter - 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 - MCU_DRVreader - Select the drive strength of the pad during sleep mode. A higher value corresponds with a higher strength.
 
- Field - MCU_DRVwriter - Select the drive strength of the pad during sleep mode. A higher value corresponds with a higher strength.
 
- Field - MCU_IEreader - Input enable of the pad during sleep mode. 1: input enabled; 0: input disabled.
 
- Field - MCU_IEwriter - Input enable of the pad during sleep mode. 1: input enabled; 0: input disabled.
 
- Field - MCU_OEreader - Output enable of the pad in sleep mode. 1: enable output; 0: disable output.
 
- Field - MCU_OEwriter - Output enable of the pad in sleep mode. 1: enable output; 0: disable output.
 
- Field - MCU_SELreader - Select the IO_MUX function for this signal. 0 selects Function 0, 1 selects Function 1, etc.
 
- Field - MCU_SELwriter - Select the IO_MUX function for this signal. 0 selects Function 0, 1 selects Function 1, etc.
