Coprocessor Error (COPROC_ERR) — WO. Any value written to this register will cause IGNNE#
to go active, if FERR# had generated an internal IRQ13. For FERR# to generate an internal IRQ13,
the COPROC_ERR_EN bit (Device 31:Function 0, Offset D0, Bit 13) must be 1.
Reserved
Full Reset (FULL_RST) — R/W. This bit is used to determine the states of SLP_S3#, SLP_S4#,
and SLP_S5# after a CF9 hard reset (SYS_RST =1 and RST_CPU is set to 1), after PWROK going
low (with RSMRST# high), or after two TCO timeouts.
0 = ICH6 will keep SLP_S3#, SLP_S4# and SLP_S5# high.
1 = ICH6 will drive SLP_S3#, SLP_S4# and SLP_S5# low for 3 – 5 seconds.
NOTE: When this bit is set, it also causes the full power cycle (SLP_S3/4/5# assertion) in response
Reset CPU (RST_CPU) — R/W. When this bit transitions from a 0 to a 1, it initiates a hard or soft
reset, as determined by the SYS_RST bit (bit 1 of this register).
System Reset (SYS_RST) — R/W. This bit is used to determine a hard or soft reset to the
processor.
0 = When RST_CPU bit goes from 0 to 1, the ICH6 performs a soft reset by activating INIT# for 16
1 = When RST_CPU bit goes from 0 to 1, the ICH6 performs a hard reset by activating PLTRST#

and SUS_STAT# active for about 5-6 milliseconds, however the SLP_S3#, SLPS4# and
SLP_S5# will NOT go active. The ICH6 main power well is reset when this bit is 1. It also resets
the resume well bits (except for those noted throughout the Datasheet).
