SLP_S4#Min. Assertion Width
SPL_S4# is a signal for power plane control. This signal shuts off power to all
non-critical systems when in the S4 (Suspend to disk) or S5 (Soft off) state. This
setting indicates minimum assertion width of the SLP_S4# signal to ensure that
the DRAMs have been safety power-cycled.
