Hello,

I think I made the IC connection correctly. I connected the TMS, TCK, TDO and TDI connections from the blaster. I made the voltage connection on the blaster. but there is a situation that makes me think. I saw it while researching on the forums. Can the JTAG outputs be disabled when first programming this IC? Or can the IC be encrypted? Is there a status of being protected against reading?
