Overview of the ARM Pins#
In the following table you will find an overview of the pin mapping of the SoC MIO pins (fixed pins of the SoC’s Processing System). All connector-accessible MIO pins – i.e., those having an X… assignment in column CB-Pin – are labeled with the associated net label/name (of the carrier board) in the fifth column and the connector pin in the CB-Pin column (CB –> Carrier Board). The connectivity between MIO pins and the frontpanel I/Os – four user LEDs and three buttons – is shown by column FP_.
