I think that each SLEEP# and POWER# outputs are connected internally 5.6kohm resistors for pull-up and pull-down.

Is it correct?

Hello Inoue-san,

- The pull-up/down resistors that you have mentioned refer to the internal pull-up/down.

- When a GPIO is to be used as an output pin, there is no need for an external pull-up/down to be connected.

- When a GPIO is configured as an input pin, there should be a pull-up/pull-down present on the pin so that the pin is in a known state nd not left floating.

Best regards,
