CAUTION
Although acceptable by some EPROM programmers, the signature mode cannot be used on any
E1x
device. The signature mode will input a high-level voltage (12.5 V
dc
) onto pin A9. Since this pin is not
designed for high voltage, the cell will be damaged. To prevent an accidental application of voltage,
Texas Instruments has inserted a 3.9 k
resistor between pin A9 of the TI programmer socket and the
programmer itself.
