It is described about "CYUSB3012 and CYUSB3014 Pin List" in the FX3 datasheet.
However, the BGA pin numbers are blank in some places.I will attach the example with red frame part.
How should I understand the blank pins?
For BGA pins list in FX3 datasheet, please only refer only to the BGA pin numbers listed (eg: F10, F9 and so on) and the corresponding Power Domain, I/O, name and description. All the 121 pins are listed using their respective pin numbers.
The blanks in the BGA pin list can be ignored.
