* GPIO name legend: proper name = the GPIO line is used as GPIO |
|
* NC = not connected (pin out but not routed from the chip to |
|
* anything the board) |
|
* "[PER]" = pin is muxed for [peripheral] (not GPIO) |
|
* LSEC = Low Speed External Connector |
|
* HSEC = High Speed External Connector |
|
* |
|
* Line names are taken from the schematic "sophon-edge-schematics" |
|
* version, 1.0210. |
|
* |
|
* For the lines routed to the external connectors the |
|
* lines are named after the 96Boards CE Specification 1.0, |
|
* Appendix "Expansion Connector Signal Description". |
|
* |
|
* When the 96Board naming of a line and the schematic name of |
|
* the same line are in conflict, the 96Board specification |
|
* takes precedence. This is only for the informational |
|
* lines i.e. "[FOO]", the GPIO named lines "GPIO-A" thru "GPIO-L" |
|
* are the only ones actually used for GPIO. |
