PIC16C5X
9.1
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

QTP or ROM devices have the oscillator configuration
programmed at the factory and these parts are tested
accordingly (see "Product Identification System" dia-
grams in the back of this data sheet).
