I2C2SEL
(2)
CW2<2>
I2C2 Pin Select bit (PIC24FJXXXGA1XX devices only)
1 = Use SCL2/SDA2 pins for I
2
C™ module 2
0 = Use ASCL2/ASDA2 pins for I
2
C module 2
ICS1:ICS0 CW1<9,8>
ICD Emulator Pin Placement Select bits
11 = Emulator functions are shared with PGEC1/PGED1
10 = Emulator functions are shared with PGEC2/PGED2
01 = Emulator functions are shared with PGEC3/PGED3
00 = Reserved; do not use
IESO CW2<15> Internal External Switchover bit
1 = Two-Speed Start-up enabled
0 = Two-Speed Start-up disabled
IOL1WAY CW2<4>
IOLOCK Bit One-Way Set Enable bit
0 = The OSCCON<IOLOCK> bit can be set and cleared as needed
(provided an unlocking sequence is executed)
1 = The OSCCON<IOLOCK> bit can only be set once (provided an
unlocking sequence is executed). Once IOLOCK is set, this prevents
any possible future RP register changes
JTAGEN CW1<14> JTAG Enable bit
1 = JTAG enabled
0 = JTAG disabled
OSCIOFNC CW2<5> OSC2 Pin Function bit (except in XT and HS modes)
1 = OSC2 is clock output
0 = OSC2 is general purpose digital I/O pin
PLLDIV2:PLLDIV0
(1)
CW2<14:12> USB 96MHz PLL Prescaler Select bits
111 = Oscillator input divided by 12 (48 MHz input)
110 = Oscillator input divided by 10 (40 MHz input)
101 = Oscillator input divided by 6 (24 MHz input)
100 = Oscillator input divided by 5 (20 MHz input)
011 = Oscillator input divided by 4 (16 MHz input)
010 = Oscillator input divided by 3 (12 MHz input)
001 = Oscillator input divided by 2 (8 MHz input)
000 = Oscillator input used directly (4 MHz input)
POSCMD1:
POSCMD0
CW2<1:0> Primary Oscillator Mode Select bits
11 = Primary oscillator disabled
10 = HS Crystal Oscillator mode
01 = XT Crystal Oscillator mode
00 = EC (External Clock) mode
WDTPOST3:
WDTPOST0
CW1<3:0> Watchdog Timer Prescaler bit
1111 = 1:32,768
1110 = 1:16,384
