PIC16HV54X
2.0
The configuration word is the very first memory location
which is accessed after entering the program/verify
mode of the PIC16HV54X. It contains the two bits for
the selection of the oscillator type, the watchdog timer
enable bit, and the code protection bit. All other bits (4
through 11) are read as ’1’s.
