TD87C51FB, TD87C51FX, CHMOS Single-Chip 8-Bit Microcontroller
VCC: Supply voltage.
VSS: Circuit ground.
VSS1: Secondary ground (not on DIP devices or any 83C51FA/80C51FA device).
Provided to reduce ground bounce and improve power supply by-passing.
NOTE: This pin is not a substitution for the VSS pin.
(Connection not necessary for proper operation.) Port 0: P
