Configuration Bits
Configuration bits can be programmed to select various
device configurations. Two bits are for the selection of
the oscillator type and one bit is the Watchdog Timer
enable bit. Nine bits are code protection bits for the
PIC16C54A,
PIC16CR54A,
PIC16CR54C,
PIC16C55A,
PIC16CR56A,
PIC16C57C,

One bit is for code protection for the PIC16C54,
PIC16C55,
PIC16C56
(Register 9-2).
QTP or ROM devices have the oscillator configuration
programmed at the factory and these parts are tested
PIC16C54C,
accordingly (see "Product Identification System" dia-
