These three-state outputs provide the address for the current bus cycle, ex-
These three-state bidirectional signals provide the general-purpose data path
These three-state outputs indicate the number of bytes remaining to be trans-
ferred for the current bus cycle. With A0, A1, DSACK0, DSACK1, and STERM,

their use in dynamic bus sizing.
These three-state outputs identify the address space of the current bus cycle.
Table 4-1 shows the relationship of the function code signals to the privilege
cept in the CPU address space. Refer to 4.2 ADDRESS SPACE TYPES for more
information on the CPU address space. A31 is the most significant address
signal, Refer to 7.1.2 Address Bus for information on the address bus and
its relationship to bus operation.

24, or 32 bits of data per bus cycle. D31 is the most significant bit of the data
bus. Refer to 7.1.4 Data Bus for more information on the data bus and its
