USB Clock Selection bit
(PIC18F2455/2550/4455/4550, PIC18F2458/2553/4458/4553 and
PIC18F2450/4450 devices only)
Selects the clock source for full-speed USB operation:
1 = USB clock source comes from the 96 MHz PLL divided by 2
0 = USB clock source comes directly from the OSC1/OSC2 oscillator block;
CPU System Clock Selection bits
(PIC18F2455/2550/4455/4550, PIC18F2458/2553/4458/4553 and
PIC18F2450/4450 devices only)
11 = CPU system clock divided by 4
10 = CPU system clock divided by 3
01 = CPU system clock divided by 2
00 = No CPU system clock divide
Oscillator Selection bits
(PIC18F2455/2550/4455/4550, PIC18F2458/2553/4458/4553 and
PIC18F2450/4450 devices only)
Divider must be selected to provide a 4 MHz input into the 96 MHz PLL:
111 = Oscillator divided by 12 (48 MHz input)
110 = Oscillator divided by 10 (40 MHz input)
101 = Oscillator divided by 6 (24 MHz input)
100 = Oscillator divided by 5 (20 MHz input)
011 = Oscillator divided by 4 (16 MHz input)
010 = Oscillator divided by 3 (12 MHz input)
001 = Oscillator divided by 2 (8 MHz input)
000 = No divide – oscillator used directly (4 MHz input)
USB Voltage Regulator Enable bit
(PIC18F2455/2550/4455/4550, PIC18F2458/2553/4458/4553 and
PIC18F2450/4450 devices only)
1 = USB voltage regulator is enabled
0 = USB voltage regulator is disabled
Brown-out Reset Voltage bits
11 = V
10 = V
01 = V
00 = V
Brown-out Reset Enable bits
11 = Brown-out Reset is enabled in hardware only (SBOREN is disabled)
10 = Brown-out Reset is enabled in hardware only and disabled in Sleep mode
01 = Brown-out Reset is enabled and controlled by software (SBOREN is
00 = Brown-out Reset is disabled in hardware and software
Power-up Timer Enable bit
1 = PWRT is disabled
0 = PWRT is enabled
