Rl_OUT*/
Ring Indicate Output / PCI Bus Interrupt B / ISA
INTB#/
Interrupt Request 10: In PCI Interrupt Signaling
IRQ10
mode, this output can be used as an interrupt
output connected to the PCI bus INTB# interrupt
line. In External-Hardware Interrupt Signaling
mode, this pin indicates interrupt request IRQ10.
SOUT#/
Serial Interrupt Output / PCI Bus Interrupt C /
INTC#/
Serial IRQ Load: In PCI Interrupt Signaling mode,
ISLD
this output can be used as an interrupt output
connected to the PCI bus INTC# interrupt line. In
PC/PCI Serial Interrupt Signaling mode, this pin is
the serial interrupt output, SOUT#. In External-
Hardware Interrupt Signaling mode, this pin is the
load signal, ISLD, used to load the serially
transmitted interrupt data into the external serial-
to-parallel shifters.
SIN#
Serial Interrupt Input / PCI Bus Interrupt D /
/INTD#
Serial IRQ Data: In PCI Interrupt Signaling mode,
/ISDAT
his output can be used as an interrupt output
connected to the PCI bus INTD# interrupt line. In
PC/PCI Serial Interrupt Signaling mode, this pin is
the serial interrupt input, SIN#. In External-
Hardware Interrupt Signaling mode, this pin is the
IRQ vector data, ISDAT, that is serially
transmitted to the external serial-to-parallel
shifters.
CLKRUN#
Clock Run: This pin is an input to indicate the
status of PCI_CLK or an open-drain output to
request the starting or speeding up of PCI_CLK.
This pin complies with the Mobile PCI
Specification.
PCI_VCC
PCI Bus Vcc: These pins can be connected to
either a 3.3- or 5-volt power supply. The PCI bus
interface pin outputs listed in this table will operate
at the voltage applied to these pins, independent
of the voltage applied to other CL-PD6730 pin
groups.
