TMS320F28379D: Schematic net labelling

Part Number: TMS320F28379D

Hi,

I'm looking at adapting this Control Card reference design for my own daughter-card implementation.

Looking at the schematic, F2837x-180controlCARD_R1_3_SCH_02Oct2015.pdf

Can you explain the significance of labelling the nets for GPIO29-33, 37-41, 44-83, 85-87, 92-93 with a _L as opposed to those GPIO's which don't have it?

eg MCU_GPIO-93_L compared with MCU_GPIO-94

Many thanks
