I'm used to run PIC24 device family (e.g PIC24FJ256GB) at CPU freq 32MHz using the PLL.
Recently I got to use PIC24FJ256GA705 on my new project and when I read the datasheet, I found out that the PLL has mode "PLL8X" (Figure 9-2 page 108) I've 8MHz crystal at the primary clock input, so if I use this mode I should got CPU freq 8MHz x 8 = 64MHz right?
But last night when I try to blink the LED at 1 Hz using "__delay_ms(1000)", the LED won't blink.
The PLL was locked (OSCCONbits.LOCK) when checked.
So I'm just curious is anybody ever used this device at 64 MHz CPU freq???
Can this device really run at 64MHz?
