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,

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
