16F84A EEPROM Programming

[Acetronics2]

Hi, Steve

Seems impossible to write FF ( or erase ) to the EEPROM ... I had tried this way too ... memory window just can show his red face !!! no more.

I think, I have to wait for the 7.02 Release ...

Have a nice day

Hi, Everybody

Here is the answer from Microchip :


Comments:
You are correct, regarding SSR19753, even though the PIC16F84A is not mentioned. I have informed the development systems group about this.

The enhancement to erase EEPROM is planned for MPLAB IDE v7.20.

Currently:
Issuing an Erase when the device has been code protected will clear the entire device of data. A Blank Check will state the device is blank
Programming the entire device with new data will change all memory areas. If for example this data were the reset values, a Blank Check after programming would reflect the device is blank.

So must we do ...


Good quiet night to you, folks ...
