ADDRESS / DATA BUS
carries 32-bit physical addresses and 8-, 16- or 32-bit data
to and from memory. During an address (
T
a
) cycle, bits 31:2 contain a physical word
address (bits 0-1 indicate SIZE; see below). During a data (T
d
) cycle, read or write
data is present on one or more contiguous bytes, comprising AD31:24, AD23:16,
AD15:8 and AD7:0. During write operations, unused pins are driven to determinate
values.
SIZE, which comprises bits 0-1 of the AD lines during a
T
a
cycle, specifies the
number of data transfers during the bus transaction.

When the processor enters Halt mode, if the previous bus operation was a:
write — AD31:2 are driven with the last data value on the AD bus.
read — AD31:4 are driven with the last address value on the AD bus; AD3:2 are
driven with the value of A3:2 from the last data cycle.
Typically, AD1:0 reflect the SIZE information of the last bus transaction (either
instruction fetch or load/store) that was executed before entering Halt mode.
ALE

R(0)
H(Z)
P(0)
ADDRESS LATCH ENABLE
indicates the transfer of a physical address. ALE is
asserted during a
T
cycle and deasserted before the beginning of the T
d
state. It is
active HIGH and floats to a high impedance state during a hold cycle (T
h
).
ALE
O
R(1)
H(Z)
P(1)
ADDRESS LATCH ENABLE
indicates the transfer of a physical address. ALE is the
inverted version of ALE. This signal gives the 80960Jx a high degree of compatibility
with existing 80960Kx systems.
ADS
O
R(1)
H(Z)
P(1)
ADDRESS STROBE
indicates a valid address and the start of a new bus access.
The processor asserts ADS for the entire
T
a
cycle. External bus control logic typically
samples ADS at the end of the cycle.
A3:2
O
R(X)
H(Z)
P(Q)
ADDRESS3:2
comprise a partial demultiplexed address bus.
32-bit memory accesses:
the processor asserts address bits A3:2 during
T
a
. The
partial word address increments with each assertion of RDYRCV during a burst.
16-bit memory accesses:
the processor asserts address bits A3:1 during
T
a
with A1
driven on the BE1 pin. The partial short word address increments with each
assertion of RDYRCV during a burst.
8-bit memory accesses:
the processor asserts address bits A3:0 during
T
a
, with A1:0
driven on BE1:0. The partial byte address increments with each assertion of
RDYRCV during a burst.
