21164 Signal Names and Functions
4.4 21164 Signal Names and Functions
The following table defines the 21164 signal types referred to in this section:
The remaining two tables describe the function of each 21164 external signal.
Table 2 lists all signals in alphanumeric order. This table provides full signal descrip-
tions. Table 3 lists signals by function and provides an abbreviated description.

Signal
Type Count Description
addr_h<39:4>
B
36
Address bus. These bidirectional signals provide the address of
the requested data or operation between the 21164 and the sys-
tem. If
addr_h<39>
is asserted, then the reference is to non-
cached, I/O memory space.
When the byte/word instructions are enabled and
addr_h<39>
is asserted, 6 additional bits of information are communicated
over the pin bus. Two of the new bits are driven over
addr_h<38:37>
, becoming
transfer_size<1:0>
, with the fol-
lowing values:
00 Size = 8 bytes
01 Size = 4 bytes
10 Size = 2 bytes
11 Size = 1 byte
addr_bus_req_h
I
1
Address bus request. The system interface uses this signal to
gain control of the
addr_h<39:4>
,
addr_cmd_par_h
, and
cmd_h<3:0>
pins.
addr_cmd_par_h
B
1
Address command parity. This is the odd parity bit on the cur-
rent command and address buses. The 21164 takes a machine
check if a parity error is detected. The system should do the
same if it detects an error.
