In SX Microcontrollers, SX/B Compiler and SX-Key Tool, Peter Van der Zee wrote: Hi Steve; The SX-Key is VERY fussy about having solid supply at not less than 5 volts. It seems to be willing to tolerate 5.5 volts, but mine quits if it drops to 4.9 for even a very brief moment. Generally when I get the kind of errors you are describing, then cranking the supply voltage up just a hair fixes the problem.
