cant get 64mhz from pic18f14k22, anyone have working fcfx file?

[john]

i am doing something wrong but cant find out what. Cant make it work at 64mhz, max i managed was 16mhz(even if i set at 64mhz using PLL) and something is not right as it randomly reboots or wont start.
Uploading hex files with pickit3
i have attached my flowcode file.
It would be awesome if anyone could check what i have made wrong or upload .fcfx and .hex file with pic18f14k22 working at 64mhz

Hi John

Merry Christmas.

Generally speaking the chip takes four cycles per instruction so in real terms divide Oscillator Speed by four to get actual speed (see page 265 of data sheet). In your example 64MHz/4 = 16MHz

Hi, I have made some changes for you.
With these types of microcontrollers, the PLLEN within the OSCCON register must be enabled.
Can you give the attached a try, and let me know how you get on, please.
