GPRs (General Purpose Registers) and USRs (User Special Registers) are implemented without reset to save gate count. In the simulation, one would encounter unknown propagation problems by reading uninitialized GPRs/USRs. To solve this problem, these registers should be initialized to known values as:
V3m (N705, N801...)
