SWSMI_RATE_SEL — R/W. This field indicates when the SWSMI timer will time out.
Valid values are:
00 = 1.5 ms ± 0.6 ms
01 = 16 ms ± 4 ms
10 = 32 ms ± 4 ms
11 = 64 ms ± 4 ms
These bits are not cleared by any type of reset except RTCRST#.
SLP_S4# Minimum Assertion Width — R/W. This field indicates the minimum
assertion width of the SLP_S4# signal to ensure that the DRAMs have been safely
power-cycled.
Valid values are:
11 = 1 to 2 seconds
10 = 2 to 3 seconds
01 = 3 to 4 seconds
00 = 4 to 5 seconds
This value is used in two ways:
1.
2.
RTCRST# forces this field to the conservative default state (00b)
SLP_S4# Assertion Stretch Enable — R/W.
0 = The SLP_S4# minimum assertion time is 1 to 2 RTCCLK.
1 = The SLP_S4# signal minimally assert for the time specified in bits 5:4 of this
This bit is cleared by RTCRST#
register.
If the SLP_S4# assertion width is ever shorter than this time, a status bit is set
for BIOS to read when S0 is entered.
If enabled by bit 3 in this register, the hardware will prevent the SLP_S4# signal
from deasserting within this minimum time period after asserting.
