// PIC18F14K50 Configuration Bit Settings
// 'C' source line config statements
// CONFIG1L
#pragma config CPUDIV = NOCLKDIV// CPU System Clock Selection bits (No CPU System Clock divide)
#pragma config USBDIV = OFF     // USB Clock Selection bit (USB clock comes directly from the OSC1/OSC2 oscillator block; no divide)

// CONFIG1H
#pragma config FOSC = IRC       // Oscillator Selection bits (Internal RC oscillator)
#pragma config PLLEN = OFF      // 4 X PLL Enable bit (PLL is under software control)
#pragma config PCLKEN = ON      // Primary Clock Enable bit (Primary clock enabled)
#pragma config FCMEN = OFF      // Fail-Safe Clock Monitor Enable (Fail-Safe Clock Monitor disabled)

// CONFIG3H
#pragma config HFOFST = ON      // HFINTOSC Fast Start-up bit (HFINTOSC starts clocking the CPU without waiting for the oscillator to stablize.)
