Table 4. Processor/PIIX4E/M Sideband Signal Descriptions
Description
Numeric Coprocessor Error: This pin functions as a FERR# signal supporting
coprocessor errors. This signal is tied to the coprocessor error signal on the processor
and is driven by the processor to the PIIX4E/M.
Processor Reset: The signal is not used in the Celeron processor mobile module
MMC-1.
Ignore Error: This open-drain signal is connected to the Ignore Error pin on the
processor and is driven by the PIIX4E/M.
Initialization: INIT# is asserted by the PIIX4E/M to the processor for system
initialization. This signal is an open-drain.
Processor Interrupt: INTR is driven by the PIIX4E/M to signal the processor that an
interrupt request is pending and needs to be serviced. This signal is an open-drain.
Non-Maskable Interrupt: NMI is used to force a non-maskable interrupt to the
processor. The PIIX4E/M ISA bridge generates NMI when either SERR# or IOCHK# is
asserted, depending on how the NMI Status and Control Register is programmed. This
signal is an open-drain.
Address Bit 20 Mask: When enabled, this open-drain signal causes the processor to
emulate the address wraparound at 1 MB, which occurs on the Intel 8086 processor.
System Management Interrupt: SMI# is an active low synchronous output from the
PIIX4E/M that is asserted in response to one of many enabled hardware or software
events. The SMI# open-drain signal can be an asynchronous input to the processor.
However, in this chip set SMI# is synchronous to PCLK.
Stop Clock : STPCLK# is an active low synchronous open-drain output from the
PIIX4E/M that is asserted in response to one of many hardware or software events.
STPCLK# connects directly to the processor and is synchronous to PCICLK. When the
processor samples STPCLK# asserted, it responds by entering a low power state (Quick
Start). The processor will only exit this mode when this signal is deasserted.
