1.4 IO Pins Assignment
The RTL8773E Motherboard is designed to fit RTL8773E EVB daughter board. All
common interfaces installed on evaluation board are available to each IO pin of
RTL8773E chip by connecting control jumpers to different RTL8773E chip’s IOs.
The default pin assignment is performed by directly shorting pins of RTL8773E
Motherboard and common interfaces on control jumper.
For example, J3 is used for LEDs’ and KEY s’ control. Short Pin1 and Pin2 on control
jumper, LED1 is controlled by M0_1 of RTL8773E Motherboard
