TABLE 28-2: dsPIC33F CONFIGURATION BITS DESCRIPTION (CONTINUED)

Bit Field

Register RTSP Effect

Description

GSS<1:0>

FGS

Immediate

General Segment Code-Protect bit

11 = User program memory is not code-protected

10 = Standard security

0x = High security

GWRP

FGS

Immediate General Segment Write-Protect bit

1 = User program memory is not write-protected

0 = User program memory is write-protected

IESO

FOSCSEL

Immediate

Two-speed Oscillator Start-up Enable bit

1 = Start-up device with FRC, then automatically switch to the

user-selected oscillator source when ready

0 = Start-up device with user-selected oscillator source

FNOSC<2:0>

FOSCSEL

If clock

switch is

enabled,

RTSP effect

is on any

device

Reset;

otherwise,

Immediate

Initial Oscillator Source Selection bits

111 = Internal Fast RC (FRC) oscillator with postscaler

110 = Internal Fast RC (FRC) oscillator with divide-by-16

101 = LPRC oscillator

100 = Secondary (LP) oscillator

011 = Primary (XT, HS, EC) oscillator with PLL

010 = Primary (XT, HS, EC) oscillator

001 = Internal Fast RC (FRC) oscillator with PLL

000 = FRC oscillator

FCKSM<1:0>

FOSC

Immediate

Clock Switching Mode bits

1x = Clock switching is disabled, Fail-Safe Clock Monitor is disabled

01 = Clock switching is enabled, Fail-Safe Clock Monitor is disabled

00 = Clock switching is enabled, Fail-Safe Clock Monitor is enabled

IOL1WAY

FOSC

Immediate Peripheral Pin Select Configuration bit

1 = Allow only one reconfiguration

0 = Allow multiple reconfigurations

OSCIOFNC

FOSC

Immediate OSC2 Pin Function bit (except in XT and HS modes)

1 = OSC2 is clock output

0 = OSC2 is general purpose digital I/O pin

POSCMD<1:0> FOSC

Immediate

Primary Oscillator Mode Select bits

11 = Primary oscillator disabled

10 = HS Crystal Oscillator mode

01 = XT Crystal Oscillator mode

00 = EC (External Clock) mode

FWDTEN

FWDT

Immediate

Watchdog Timer Enable bit

1 = Watchdog Timer always enabled (LPRC oscillator cannot be disabled.

Clearing the SWDTEN bit in the RCON register has no effect.)

0 = Watchdog Timer enabled/disabled by user software (LPRC can be

disabled by clearing the SWDTEN bit in the RCON register)

WINDIS

FWDT

Immediate Watchdog Timer Window Enable bit

1 = Watchdog Timer in Non-Window mode

0 = Watchdog Timer in Window mode

WDTPRE

FWDT

Immediate Watchdog Timer Prescaler bit

1 = 1:128

0 = 1:32

Note 1: This Configuration register is not available on dsPIC33FJ32MC302/304 devices.
