Of course instruction and data words don't have to

of the PIC microcontrollers have 8bit data and 14 bit instructions
Likewise, the GI 1600 (used in the Intellivision, among other things) has
16-bit data words and 10-bit instructions. Apparently, the Intellivision
designers didn't want to waste 6 bits of ROM for each instruction to gain
the benefit of being able to store 16-bit data, so Intellivision ROM
cartridges are only 10 bits wide.
