PLL enable with PIC 18F46K22

#1 Post by saharul » 26 Jun 2018 09:33

hi,

i have some confusion over the PLL enabled. My undestanding the same will be multipled by 4. I tried writing some codeand run EASYPIC7 with 20Mhz crystal and PLL disbaled. The same be tested using crystal of 12 Mhz and PLL enabled. Supposed the code should run faster with 12 Mhz and PLL enabled. But when i hooked out Oscilloscope, i realized the 20 Mhz is run faster.

What when wrong?

Many Thanks :D :D :D

In the program as below to make PORTA.B0 on and off to check the speed.

Code: Select all
