Downloaded the Tools to get an overview on how the peripheral pins would look on a lqfp100 package.
Selected the LPC54606J512BD100.
Started assigning pins, things where different in the data-sheet.
Started from scratch.
Select: USBFSH -> first two pins are : USB0_DP  & USB_DM 
Selected (and assigned)
On the package windows the Top left pin is assigned to USB_DM this is Pin 100, USB0_DP is assigned to in 99 (package only)
In the Left (pins) window they appear the right way.
However the pins window i don't see 100 pins but a total of 102 pins as pin 30 is listed twice (VSSA & VREFN), same for pin 55 (pio1_1 & wakeup)
Could be a user error as i am new and just selected a random uC but i can't see what i did wrong.
