Branch

PC = [PC+1+X]

The Branch instruction allows an "n-way" branch on the contents of the X register. A Branch instruction must always be followed by a list of one or more program labels used as arguments in Target instructions. Example

   Branch
   Target      Again         ;target if X=0
   Target      More          ;target if X=1
   Target      Orless        ;target if X=2

In the example, the program will transfer to label Again if X=0, to More if X=1 and to Orless if X=2.

For any other value of X the results are unpredictable in SPLat hardware.

On 8 bit controllers (green boards), there may be up to 127 Target instructions following it.  On 32 bit controllers (black boards) there may be 256 Targets.

When using Branch and Target take extra care. If the offset in X points to a line past the end of the Target list, there is no guarantee of what will happen.  Your controller will either crash or behave very strangely.
