mode.
Local Clock
Reference output clock derived from the
PCI clock.
Address bus
These input address lines select one of
the internal registers for read or write
access.
Note: Only LA(7:0) are evaluated during
read/write accesses to the TE3-CHATT.
In local bus master mode the address
lines are output. If local bus master
functionality is disabled these pins are
input only.
Data Bus
Bidirectional tri-state data lines.
Chip Select
This active low signal selects the TE3-
CHATT as bus slave for read/write
operations.
