Read Identifier Codes Operation
Write Operation
Command Definitions
The read identifier codes operation outputs the manufacturer and device codes (see Table 4). Using the
manufacturer and device codes, automated test equipment (ATE) or PROM programmer software can
confirm the proper device ID.
The CUI does not occupy a specific addressable memory location. It is written to when WE# is active
and OE# = V
command are latched on the WE# rising edge.
Flash core programming commands in A/A Mux mode are identical to commands for the FWH mode.
Refer to Section 4 of this document.
Electrical Characteristics in A/A Mux Mode
Certain specifications differ from the previous sections, when programming in the A/A Mux mode. The
following subsections provide this data. Any information not provided here is not specific to the A/A
Mux mode. Refer to Section 5 of this document and use the Intel FWH mode specifications.
