MFUNC0
154
F15
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. Refer to the multifunction routing registerdescription on page 62 for
configuration details.
MFUNC1
155
E17
I/O
Multifunction terminal 1. MFUNC1 can be configured as parallel PCI interrupt INTB, GPI1,
GPO1, socket activity LED output, ZV switching outputs, CardBus audio PWM, GPE, or a
parallel IRQ. Refer to the multifunction routing registerdescription on page 62 for
configuration details.
Serial data (SDA). When the serial bus mode is implemented by pulling the LATCH terminal
low, the MFUNC1 terminal provides the SDA signaling. The two pin serial interface is used to
load the subsystem identification and other register defaults from an EEPROM after a PCI
reset. Refer to the serial bus interface implementationdescription on page 29 for details on
other serial bus applications.
MFUNC2
157
A16
I/O
Multifunction terminal 2. MFUNC2 can be configured as GPI2, GPO2, socket activity LED
output, ZV switching outputs, CardBus audio PWM, GPE, or a parallel IRQ. Refer to the
multifunction routing registerdescription on page 62 for configuration details.
MFUNC3
158
C15
I/O
Multifunction terminal 3. MFUNC3 can be configured as a parallel IRQ or the serialized
interrupt signal IRQSER. Refer to the multifunction routing registerdescription on page 62 for
configuration details.
MFUNC4
159
E14
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, or a parallel IRQ. Refer
to the multifunction routing registerdescription on page 62 for configuration details.
Serial clock (SCL). When the serial bus mode is implemented by pulling the LATCH terminal
low, the MFUNC4 terminal provides the SCL signaling. The two pin serial interface is used to
load the subsystem identification and other register defaults from an EEPROM after a PCI
reset. Refer to the serial bus interface implementationdescription on page 29 for details on
other serial bus applications.
MFUNC5
160
F13
I/O
Multifunction terminal 5. MFUNC5 can be configured as GPI4, GPO4, socket activity LED
output, ZV switching outputs, CardBus audio PWM, GPE, or a parallel IRQ. Refer to the
multifunction routing registerdescription on page 62 for configuration details.
MFUNC6
161
B15
I/O
Multifunction terminal 6. MFUNC6 can be configured as a PCI CLKRUN or a parallel IRQ.
Refer to the multifunction routing registerdescription on page 62 for configuration details.
RI_OUT/PME
163
C14
O
Ring Indicate Out and Power Management Event Output. Terminal provides an output for
ring-indicate or PME signals.
SPKROUT
149
G15
O
Speaker output. SPKROUT is the output to the host system that can carry SPKR or CAUDIO
through the PCI1221 from the PC Card interface. SPKROUT is driven as the exclusive-OR
combination of card SPKR//CAUDIO inputs.
SUSPEND
156
D19
I
Suspend. SUSPEND is used to protect the internal registers from clearing when the PRST
signal is asserted. See suspend modedescription on page 40 for details.
