4.17 Usage of CPU Pins
Almost all pins of the i.MX RT1062 MCU are directly available on the SODIMM expansion connector.
In a few cases are pins used for dedicated functionality like the Ethernet interface, EcoXiP interface
and on-board SDRAM. These pins are not available on the SODIMM expansion connector. The table
below lists all pins and their possible restrictions.
Before using a signal, make sure usage does not collide with functions on the iMX OEM Carrier Board.
