This command initializes the contents of a specified GPRM register with one of the following:

1) the contents of another GPRM register, or
2) a 16-bit constant value.

The GPRM register can be initialized in the register mode or counter mode. In register mode, a GPRM register is used as a temporary location to hold a 16-bit value which can be accessed by any VM command. In counter mode, its contents are increased by 1 (one) for each elapsed second. This effectively is a count-up counter and can be used for timing applications.

This command can be combined with the Compare GPRM operations for conditional branching. When combining, this command is executed only if the result of the comparison is true.

1) Compare to another GPRM register and SetGPRMMD
2) Compare to another SPRM register and SetGPRMMD
