Notes: 1. Timing and switching specifications for the register listed above are critical for proper operation of the DDR2
SDRAM registered DIMMs. These are meant to be a subset of the parameters for the specific device used on the
module. Detailed information for this register is available in JEDEC standard JESD82.
