These are the defaults I use on most all USB projects. 18F4550 target with a
20MHz primary crystal osc.
Code:
CONFIG PLLDIV=5,CPUDIV=OSC1_PLL2,USBDIV=2,FOSC=HSPLL_HS,FCMEM=OFF,IESO=OFF
CONFIG VREGEN=ON,CCP2MX=ON,WDT=OFF,WDTPS=32768,PBADEN=OFF,PWRT=OFF,MCLRE=ON
CONFIG LPT1OSC=OFF,BOR=ON,BORV=2,STVREN=ON,LVP=OFF,ICPRT=OFF,XINST=OFF,DEBUG=OFF
CONFIG WRTB=ON
You would use Define OSC 48 since the CPU core is running at 48MHz.
