The User LEDs may be isolated from the Main MCU, so the associated ports can be used for other
purposes. To separate LED1 from P415, Trace Cut Jumper E27 must be open. To separate LED2 from
P404, Trace Cut Jumper E26 must be open. To separate LED3 from P400, Trace Cut Jumper E28 must be
open.

The User Switches S1 and S2 may be isolated from the Main MCU, so the associated ports can be used for
other purposes. To separate S1 from P005, Trace Cut Jumper E31 must be open. To separate S2 from
P600, Trace Cut Jumper E32 must be open.
