Pic 18F4550 oscilators (basics)
I am programing with assembler language (MPLAB).
1.If i use 10MHz crystal oscilator (osci1/osci2, 22pF).
;CONFIG FOSC = HS
;CONFIG FOSC = HSPLL_HS
What else must i define to determinate at what frequency CPU will run with examples of config above?
2. What is the max internal frequency this PIC can run and what what must i write below
CONFIG FOSC = ............?
What else must i define to determinate at what frequency CPU will run with examples of config above?
And where do i find the CONFIG list?
Tell me also pleas the path to appropriate zone for PIC microcontrollers questions?
I really hope that i will find help here on expert exchange.
Thank you

tx for feedback - let it oscillate now !

Thank you.
Next was mising to work with 40MHz:
CONFIG CPUDIV = OSC4_PLL6 ;
