Differential Pair Labeling
I/Os with Lxxy_# are part of a differential pair. ‘L’ indicates
differential capability. The “xx” field is a two-digit integer,
unique to each bank that identifies a differential pin-pair.
The ‘y’ field is either ‘P’ for the true signal or ‘N’ for the
inverted signal in the differential pair. The ‘#’ field is the I/O
bank number.
The pin name suffix has the following significance.

Along with all the other VCCO pins in the same bank, this pin supplies
power to the output buffers within the I/O bank and sets the input threshold
voltage for some I/O standards. See the
section in Module 2 for details.
This package pin is not connected in this specific device/package
combination but may be connected in larger devices in the same package.

"xx" is a two-digit integer, unique for each bank, that
identifies a differential pin-pair.
‘y’ is replaced by ‘P’ for the true signal or ‘N’ for the
inverted. These two pins form one differential pin-pair.
‘#’ is an integer, 0 through 3, indicating the associated
I/O bank.
‘L’ indicates that the pin is part of a differential pair.
