otherwise,
General Segment Code-Protect bit
1 = User program memory is not code-protected
0 = Code protection is enabled for the entire program memory space
General Segment Write-Protect bit
1 = User program memory is not write-protected
0 = User program memory is write-protected
Two-speed Oscillator Start-up Enable bit
1 = Start-up device with FRC, then automatically switch to the
0 = Start-up device with user-selected oscillator source
PWM Lock Enable bit
1 = Certain PWM registers may only be written after key sequence
0 = PWM registers may be written without key
Watchdog Window Select bits

Watchdog Timer Enable bit
1 = Watchdog Timer always enabled (LPRC oscillator cannot be disabled.
0 = Watchdog Timer enabled/disabled by user software (LPRC can be disabled
Watchdog Timer Window Enable bit
1 = Watchdog Timer in Non-Window mode
0 = Watchdog Timer in Window mode
user-selected oscillator source when ready
Clearing the SWDTEN bit in the RCON register will have no effect.)
