,/* Oddities */
* Conditional jumps are only 8-bit relative. And unconditional jumps are only 16-bit absolute.
* ADC is the only command for addition. To perform an addition without carry, the carry flag must be cleared manually first. Same with SBC for subtract.
* The CLV (Clear Overflow Flag) instruction exist but not the SEV (Set Overflow Flag) instruction.
