Version: **

I/O drive mode

Set the drive mode to analog HIGH-Z mode before entering the Deep Sleep mode. But if it is connected to an external or internal pull-up and pull-down resister, set the I/O drive mode to the following drive modes:

  • “Open drain, drives High” for external pull-down, I/O state = 0
  • “Open drain, drives Low” for external pull-up, I/O state = 1
  • “Resistive pull-up” for internal pull-up, I/O state = 1
  • “Resistive pull-down” for internal pull-down, I/O state = 0

System clock

The Deep Sleep function stops the system main clock automatically. Therefore, it is not required to configure the system main clock manually.
