STPCLK_DEL — R/W. This field selects the AC timing value for t190 (CPUSLP# inactive to
STPCLK# inactive). The default value of 0Dh yields a default of approximately 50.045
microseconds. The maximum value of 3Fh will result in a time of 245 microseconds.
NOTE: Software must program the value to a range that can be tolerated by the associated
GPI15 Route — R/W. See bits 1:0 for description.
GPI2 Route — R/W. See bits 1:0 for description.
GPI1 Route — R/W. See bits 1:0 for description.
GPI0 Route — R/W. GPIO[15:0] can be routed to cause an SMI or SCI when the GPI[n]_STS bit is
set. If the GPIO is not set to an input, this field has no effect.
If the system is in an S1
Wake event, even if the GPI is NOT routed to cause an SMI# or SCI.
00 = No effect.
