I am a little confused.

I have just read the programming data sheet for the 16C84 where it states that when you read
the retrieved data from the program memory it is in  a 14-bit format.

However if I read an empty PIC  the word is 3FFF which requires only 13 bits. A 14-bit word would give
me a maximum of 7FFF.

Can sombody explain this please?

Have a happy Christmas
