i purchased a flash module am29f040b-90J its access time is 90ns, but the microcontroller has 80/60ns instruction cyle. Can I use this flash with the microcontroller? Or is it preferrable that I purchase a faster flash? The way I'm talking to flash is via a gui called BootLoad, but I haven't been able to see the program run purely thru flash. Which leads to my next question. I'm experimenting with the sample code called "Blinky". I figure that if the code is in flash, then I should be able to power up the MCB167NET and automatically see the led lights turn on as the "blinky" program would have it. Has anyone gotten this to work, or know what hex values to input in that gui for: BUSCON0 SYSCON0 I've been reading the Manual and have determined that BUSCON0:0XC69F and SYSCON0:0X887. I show that the program was loaded succesfully and then am prompted to "reset processor and start program". So I hit reset, but don't see the led lights turn on and off as the "blinky" program would have them do. So, perhaps my hex numbers are wrong? Or, what am I doing wrong? Are there any other registers I also need to change? I know these are a lot of questions. If you know the answer to one of them, it would help me some. Any help is good. Thank you all in advance.
