Hi, I'm using MPLAB v4.99.07 for Code development. (Didn't have time to download the latest version) The Flash Read,Write functions don't seem to work in the Simulator. I'm using the example code given by Microchip in their 16f877 data sheet. Has this problem been fixed in the latest version of MPLAB ?
