The number shown in bold indicates the maximum number of I/O and input-only pins. The number shown in (italics) indicates the number
of input-only pins. The differential (Diff) input-only pin count includes both differential pairs on input-only pins and differential pairs on I/O pins
within I/O banks that are restricted to differential inputs.
