I/O
DESCRIPTION
CLK_48_RSVD 85 H10 —
No connect. These terminals have no connection anywhere within the package.
Terminals H10 on the GGU package and 85 on the PGE package will be used as a
48-MHz clock input on future-generation devices.
MFUNC0 58 K07 F05 I/O
Multifunction terminal 0. MFUNC0 can be configured as parallel PCI interrupt INTA,
GPI0, GPO0, socket activity LED output, ZV switching output, CardBus audio PWM,
GPE
, or a parallel IRQ. See Section 4.30, Multifunction Routing Register, for
configuration details.
MFUNC1 59 N09 G06 I/O
Multifunction terminal 1. MFUNC1 can be configured as GPI1, GPO1, socket activity
LED output, D3_STAT
, ZV switching output, CardBus audio PWM, GPE, or a parallel
IRQ. See Section 4.30, Multifunction Routing Register, for configuration details.
Serial data (SDA). When VCCD0
and VCCD1 are detected high after a global reset, the
MFUNC1 terminal provides the SDA signaling for the serial bus interface. The
two-terminal serial interface loads the subsystem identification and other register
defaults from an EEPROM after a global reset. See Section 3.6.1, Serial Bus Interface
Implementation, for details on other serial bus applications.
MFUNC2 63 L09 F03 I/O
Multifunction terminal 2. MFUNC2 can be configured as GPI2, GPO2, socket activity
LED output, ZV switching output, CardBus audio PWM, GPE
, RI_OUT, D3_STAT, or a
parallel IRQ. See Section 4.30, Multifunction Routing Register, for configuration details.
MFUNC3/
IRQSER
64 K10 F02 I/O
Multifunction terminal 3. MFUNC3 can be configured as a parallel IRQ or the serialized
interrupt signal IRQSER. This terminal is IRQSER by default. See Section 4.30,
Multifunction Routing Register, for configuration details.
MFUNC4 67 M10 G05 I/O
Multifunction terminal 4. MFUNC4 can be configured as PCI LOCK, GPI3, GPO3, socket
activity LED output, ZV switching output, CardBus audio PWM, GPE
, D3_STAT,
RI_OUT
, or a parallel IRQ. See Section 4.30, Multifunction Routing Register, for
configuration details.
Serial clock (SCL). When VCCD0
and VCCD1 are detected high after a global reset, the
MFUNC4 terminal provides the SCL signaling for the serial bus interface. The
two-terminal serial interface loads the subsystem identification and other register
defaults from an EEPROM after a global reset. See Section 3.6.1, Serial Bus Interface
Implementation, for details on other serial bus applications.
MFUNC5 68 N12 F01 I/O
Multifunction terminal 5. MFUNC5 can be configured as GPI4, GPO4, socket activity
LED output, ZV switching output, CardBus audio PWM, D3_STAT
, GPE, or a parallel
IRQ. See Section 4.30, Multifunction Routing Register, for configuration details.
MFUNC6/
CLKRUN
69 L10 H06 I/O
Multifunction terminal 6. MFUNC6 can be configured as a PCI CLKRUN or a parallel
IRQ. See Section 4.30, Multifunction Routing Register, for configuration details.
RI_OUT / PME 57 M08 J03 O
Ring indicate out and power management event output. Terminal provides an output for
ring- indicate or PME
signals.
SPKROUT 61 M09 E02 O
Speaker output. SPKROUT is the output to the host system that can carry SPKR or
CAUDIO through the controller from the PC Card interface. SPKROUT is driven as the
exclusive-OR combination of card SPKR//CAUDIO inputs.
SUSPEND 65 N10 G03 I
Suspend. SUSPEND protects the internal registers from clearing when the GRST or
PRST
signal is asserted. See Section 3.8.5, Suspend Mode, for details.
