Example 4 — Setting the PC and Executing the Program

This example sets the PC and begins executing the program loaded in example 3. The PC (at lo-

cation 5EH) must be set at 400H to tell the RISM where to begin execution of the program. The

WSR and PSW are automatically set to their default values (1000H and 200H, respectively), but

can be changed in this same manner. No OTPROM locations are changed, so V

+12.5 volts or +5 volts.
