You can change the three main registers: a, s and pc, although it is not
recommended that you do this unless you really know what you are doing.
Following are some examples of putting a new value into a, s and pc:
>> a=873
>> a=-1
>> s=65536u
>> pc=4095
The program counter cannot be given a negative number, and its maximum value is 4095, since there are 4096 words in memory. |
