I had a proto board made and I am trying to program the SX Chip but I get the VPP Generation Failiure.· I am running a 103 cap·from vdd to vss and the 10k resistor on the rtcc to vdd. I have sockets for my 50m crystal and I have that disconnected. I also have the 20pf caps for the Chrystal. I am powering the chip from my LCD header SO I have 4.97 volts to the chip . I checked that>>> I also did not find in the manual or I may not have looked in the right place to know what the VPP Generation means.· Thanks
