NOTES:
1. All inputs must track VDD (pin 28) within these limits.
2. VDDPROG must be capable of supplying 500mA. VDDPROG Power Supply tolerance
±
3% (Max.)
3. See Steps 22 through 29 of the Programming Algorithm.
4. See Step 11 of the Programming Algorithm.
5. All outputs should be pulled up to VDD through a resistor of value Rn.
6. Except during programming (See Programming Cycle Waveforms).
