... The PWM signal from the CCP1 module is normally output on the CCP1/RC2 pin. However, this pin is not connected to any demo board LEDs. To output a signal on an LED pin, the Enhanced CCP module (ECCP) on the PIC18F45K20 is utilized. This functionality is selected in the upper 2 bits of CCP1CON (P1Mx), which are set to 0b01 so the modulated PWM signal appears on the P1D/RD7 which drives LED 7.
