System Data Bus. In 32-bit CPU Local Bus designs these
data lines connect directly to the processor data lines. On
the VL-Bus they connect to the corresponding buffered or
unbuffered data signal. These pins are tri-stated during
Standby mode (as are all other bus interface outputs).
PCI Bus Interface
207
RESET#
In
Reset. This input sets all signals and registers in the chip to
a known state. All outputs from the chip are tri-stated or
driven to an inactive state. This pin is ignored during
Standby mode (STNDBY# pin low). The remainder of the
system (therefore the system bus) may be powered down if
desired (all bus output pins are tri-stated in Standby mode).
201
CLK
In
Bus Clock. This input provides the timing reference for all
bus transactions. All bus inputs except RESET# and INTA#
are sampled on the rising edge of CLK. CLK may be any
frequency from DC to 33MHz.
