Introduction
This chapter contains the pinout description of the Axel ULite module, grouped in two tables (odd and even pins) that report the pin mapping of the 204-pin SO-DIMM Axel ULite connector.
Each row in the pinout tables contains the following information:
- Pin: reference to the connector pin
- Pin Name: pin (signal) name on the Axel ULite connectors
- Internal connections: connections to the Axel ULite components
- CPU.<x> : pin connected to CPU pad named <x>
- PMIC.<x> : pin connected to the Power Manager IC
- LAN.<x> : pin connected to the LAN PHY
- Ball/pin #: Component ball/pin number connected to signal
