5.4.3.3 NON-PIPELINED ADDRESS WITH
DYNAMIC DATA BUS SIZING
The physical data bus width for any non-pipelined
bus cycle can be either 32-bits or 16-bits. At the
beginning of the bus cycle, the processor behaves
as if the data bus is 32-bits wide. When the bus cy-
cle is acknowledged, by asserting READY
Y
at the
end of a T2 state, the most recent sampling of
BS16
Y
determines the data bus size for the cycle
being acknowledged. If BS16
Y
was most recently
negated, the physical data bus size is defined as
32 bits. If BS16
Y
was most recently asserted, the
size is defined as 16 bits.
When BS16
Y
is asserted and two 16-bit bus cycles
are required to complete the transfer, BS16
Y
must
be asserted during the second cycle; 16-bit bus size
is not assumed. Like any bus cycle, the second
16-bit cycle must be acknowledged by asserting
READY
Y
.
When a second 16-bit bus cycle is required to com-
plete the transfer over a 16-bit bus, the addresses
