Copy code

inout vdda1,	// User area 1 3.3V supply
    inout vdda2,	// User area 2 3.3V supply
    inout vssa1,	// User area 1 analog ground
    inout vssa2,	// User area 2 analog ground
    inout vccd1,	// User area 1 1.8V supply
    inout vccd2,	// User area 2 1.8v supply
    inout vssd1,	// User area 1 digital ground
    inout vssd2,	// User area 2 digital ground
