NOTES: 8. VCC must be applied either coincidentally or before VPP and removed either coincidentally or after VPP.
9. VPP must not be greater than 14 volts including overshoot. During CE = PGM = VIL, VPP must not be switched from 5 volts
to 12.75 volts or vice-versa.
10. During power up the PGM pin must be brought high (≥ VIH) either coincident with or before power is applied to VPP.
