GEM Registers

Table 4: Details for GEM registers. ``Group'' is the hardware component on which the register is located. ``Multiplicity'' means the number of associated registers with similar names and functionality. ``Subsections'' are the number of independent data on the register. If ``Type'' is ``int'' then the register should just be read as a number, if ``type'' is ``fields'' then the register should be broken into component fields, and if ``type'' is ``mask'' the register is a bit mask where each bit enables or disables a channel or group of channel.
