DESCRIPTION
ALE_TS
TS
I
Transfer Start: This active high signal is used to latch the contents on the
address bus ADDR[7:0]. The contents of the address bus are latched into the
ADDR[7:0] inputs on the falling edge of TS.
WR_R/W
R/W
I
Read/Write: This input pin from the local
P is used to inform the LIU
whether a Read or Write operation has been requested. When this pin is
pulled “High”, WE will initiate a read operation. When this pin is pulled
“Low”, WE will initiate a write operation.
RD_WE
WE
I
Write Enable: This active low input functions as the read or write signal from the
local
P dependent on the state of R/W. When WE is pulled “Low” (If CS
is “Low”) the LIU begins the read or write operation.
No Pin
OE
I
Output Enable: This signal is not necessary for the XRT83SL314 to interface to
the MPC8260 or MPC860 Power PCs.
PCLK
CLKOUT
I
Synchronous Processor Clock: This signal is used as the timing reference for
the Power PC synchronous mode.
RDY_TA
TA
O
Transfer Acknowledge: This active low signal is provided by the LIU device. It
indicates that the current read or write cycle is complete, and the LIU is waiting
for the next command.
