LPC47B37X

100 Pin Enhanced Super I/O for LPC Bus with SMBus Controller for Commercial Applications

SMSC -> Microchip 

Note 8: External pullups must be placed on the nKBDRST and A20M pins. These pins are General

Purpose I/Os that are inputs after an initial power-up (VTR POR). If the nKBDRST and A20M

functions are to be used, the system must ensure that these pins are high. See Section “Pins

That Require External Pullup Resistor”.

Note 9: The LED pins are powered by VTR so that the LEDs can be controlled when the part is under

VTR power.
