A PIC16 (e.g. this one) have a bunch of registers, which are 8 bit wide, and two "Configuration words" (see pages 43, 44) which are 14 bit wide.

Why do the configuration words make exception for the PIC16?


The configuration words are the same width as the program flash memory.

    \$\begingroup\$ For completeness: ...and these configuration words are mapped in program/instruction memory. They are mapped at an address location which is not accessible during normal device operation (it can be accessed only during programming mode) \$\endgroup\$
