Binary format:
is_conditional[1], instruction id[remaining bits]
is_conditional:
n: number of bits in first parameter
s: minimum number of bits required to represent (number of bits for current mode - 1)
/: integer division
Appends 2 parameters to the normal parameter list for the instruction:
First parameter:
Lowest (n-s)/2 bits:
Which bits to check
Next (n-s)/2 bits:
Value for each of the above that it should match
Remaining bits:
Bitwise offset into second parameter for value to be used
Second parameter:
Value to be used
Conditional instructions will be executed after unconditional ones
Conditional instructions will never set flags, if a conditional instruction references another, it will always be based on null flags
Exceptions:
If (s+2) > n:
Triggers `illegal instruction` exception
