TYPE
FUNCTION
PCI System Terminals
PCLK 165
I
PCI Bus clock. The PCI bus clock provides timing for all transactions on
the PCI bus. All PCI signals are sampled at the rising edge of PCLK.
RSTIN 166
I
PCI Reset. When the RSTIN signal is asserted low it causes the
PCI1131 to tri-state all output buffers and reset all internal registers.
When asserted, the 1131 device is completely nonfunctional. After
deasserting RSTIN, the PCI1131 is in its default state. When the 1131
SUSPEND mode is enabled, the device is protected from any RSTIn
reset (i.e., the 1131 internal register contents are preserved).

I/O
Address/data bus. These signals are the multiplexed PCI address and
data bus. During the address phase of a PCI cycle, AD31-0 contain a 32-
bits address or other destination information. During the data phase,
AD31-0 contain data.
