DESCRIPTION
GGU
GHK
MFUNC0
K8
60
W10
I/O
Multifunction terminal 0. MFUNC0 can be configured as parallel PCI interrupt INTA, GPI0,
GPO0, socket activity LED output, ZV switching outputs, CardBus audio PWM, GPE, or a
parallel IRQ. See Section 4.30, Multifunction Routing Register for configuration details.
MFUNC1
N9
61
V10
I/O
Multifunction terminal 1. MFUNC1 can be configured as GPI1, GPO1, socket activity LED
output, ZV switching outputs, 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 high after a PCI 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 PCI reset. See
Section 3.6.1, Serial Bus Interface Implementation for details on other serial bus applications.
MFUNC2
K9
64
P10
I/O
Multifunction terminal 2. MFUNC2 can be configured as PC/PCI DMA request, GPI2, GPO2,
socket activity LED output, ZV switching outputs, CardBus audio PWM, GPE, RI_OUT, or a
parallel IRQ. See Section 4.30, Multifunction Routing Register for configuration details.
MFUNC3
N10
65
W11
I/O
Multifunction terminal 3. MFUNC3 can be configured as a parallel IRQ or the serialized interrupt
signal IRQSER. See Section 4.30, Multifunction Routing Register for configuration details.
MFUNC4
L10
67
U11
I/O
Multifunction terminal 4. MFUNC4 can be configured as PCI LOCK, GPI3, GPO3, socket activity
LED output, ZV switching outputs, CardBus audio PWM, GPE, RI_OUT, or a parallel IRQ. See
Section 4.30, Multifunction Routing Register for configuration details.
Serial clock (SCL). When VCCD0 and VCCD1 are high after a PCI 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 PCI reset. See
Section 3.6.1, Serial Bus Interface Implementation for details on other serial bus applications.
MFUNC5
N11
68
P11
I/O
Multifunction terminal 5. MFUNC5 can be configured as PC/PCI DMA grant, GPI4, GPO4,
socket activity LED output, ZV switching outputs, CardBus audio PWM, GPE, or a parallel IRQ.
See Section 4.30, Multifunction Routing Register for configuration details.
MFUNC6
M11
69
R11
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
L8
59
P9
O
Ring indicate out and power management event output. Terminal provides an output for
ring-indicate or PME signals.
SPKROUT
M9
62
U10
O
Speaker output. SPKROUT is the output to the host system that can carry SPKR or CAUDIO
through the PCI1410 from the PC Card interface. SPKROUT is driven as the exclusive-OR
combination of card SPKR//CAUDIO inputs.
SUSPEND
L11
70
W12
I
Suspend. SUSPEND protects the internal registers from clearing when the GRST or PRST
signal is asserted. See Section 3.8.4, Suspend Mode for details.
