#98872 - I do not have an answer, just a fact whi Responding to: ???'s previous message |
On the IAP description it seems possible to do a quick erase.
Is there any problem known on using quick erase ? How long need a quick erase per block ? I do not have an answer, just a fact which is that my BP programmer erases a 668 in about 5 seconds. Is it possible that "quick erase" is only possible with a higher Vpp? I would guess so. From the absolute maximum ratings: Voltage on EA/VPP pin to VSS 0 to +13.0 V Erik |
