CL-PD6832 Pin Descriptions
Pin Name
SIN#
Serial Interrupt Input / PCI Bus Interrupt D /
/INTD#
Serial IRQ Data: In PCI Interrupt Signaling
/ISDAT
mode, this 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 and an open-drain output to
request the starting or speeding up of
PCI_CLK. This pin complies with the Mobile
PC/PCI Extended Interrupt Specification.
GNT#
Grant: This signal indicates that access to the
bus has been granted.
REQ#
Request: This signal indicates to the arbiter
that the CL-PD6832 requests use of the bus.
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-
PD6832 pin groups.
