VQFN Pad VQFN thermal pad Pad N/A Pad N/A VQFN package exposed thermal pad. TI recommends connecting to VSS.
(1) Pin Types: I = Input, O = Output, I/O = Input or Output, P = Power
(2) Because this pin is multiplexed with the JTAG function, TI recommends disabling the pin interrupt function while in JTAG debug to prevent collisions.
