19.4 Colors and symbols
Colors and symbols differentiate the pin and logic I/O macro assignments in PinEditor. The following table indicates the default colors assigned to pins.
| Color/Symbol | Definition |
|---|---|
| White border | A white border denotes a selected, assigned pin. |
| Green | A green border with a black center denotes a regular, unassigned pin. A pin with a grey or yellow border and a green center denotes a regular, assigned pin. |
| Blue | A blue border with a black center denotes a special, unassigned pin. A pin with a grey or yellow border and a blue center denotes a special, assigned pin. Special pins are pins that have some additional meaning to them. For example, pins used for JTAG are blue. When unassigned, special pins have additional descriptive text next to the pin number. |
| Grey with red center | Reserved pin. You use this pin for some specific purpose on the package, and you cannot assign it an I/O macro. Examples of such pins are ground and power. |
| Yellow | Yellow denotes locked assignments. If the assignment is selected, the symbol appears yellow. If the assignment is unselected, the border appears yellow. |
| Grey/black | A pin with a grey border and a black center denotes a pin that is not connected. You cannot use these pins, and they have no meaning. |
