3.1.4 X402 GpioD

GpioD contains 24 configurable IO Signals.

The direction of each pin can be selected individually.
The 25th data pin is dedicated for connection to a 1-wire EEPROM on an attached Adapter Board. The EEPROM contains the pin mapping configuration for the Adapter.
For more information on Function → Pin Mapping, please see 10.4.1 GPIO Port Function to Pin Mapping

Caution
As the pins of GpioD are directly connected to the SoC with minimal protection, this port must not be connected directly to other machine parts. It should always be buffered by an IO- and Protection Board. Do not connect or disconnect when the card or the other peripheral is powered. The card will be damaged!
