Download speed vs. voltage
Noticed something unusual with the download speed of program using an ICD4 and a board with a PIC24FJ256GA610.
Our current target board has a PIC supply of 2.0V. It takes about 3 1/2 minutes to download our program. A consultant we are using says it shouldn't take this long and suggested some voltage changes. So our hardware guy upped the PIC supply to 2.1V. And now our program downloads in 15 seconds! What the....?
So what is going on here? Is this documented somewhere? No changes were made to anything except for the PIC supply voltage.
