When you write to a Copper strobe address, the Copper reloads its program
counter from the corresponding  location register . The Copper can write
its own location registers and strobe addresses to perform programmed
jumps. For instance, you might  MOVE  an indirect address into the
 COP2LC  location register. Then, any  MOVE  instruction that addresses
COPJMP2 strobes this indirect address into the program counter.

There are two jump strobe addresses:

     COPJMP1/Restart Copper from address contained in  COP1LC .
     COPJMP2/Restart Copper from address contained in  COP2LC .
