Application note
ST10 RPD pin:
functionality during reset and Power Down mode
Introduction
RPD is a dedicated timing pin for the return-from-power-down circuit. Additionally, when this
pin is recognized low, a reset event is taken as asynchronous. This application note gives
advice on configuring the external circuitry connected to the RPD pin in order to make it
work properly.
The information contained in this document is valid for ST10F27x and ST10R27x.
