Table 6. Configuration Codes

Note: 1. DQ2-DQ7 are reserved

2. When STS pin is pulsing it remains Low for a typical time of 250ns.

Table 7. Read Electronic Signature

Note: 1. SBA is the Start Base Address of each block, PRD is Protection Register Data.

2. Base Address, refer to Figure 8 and Tables 8 and 9 for more information. A23 must be Low to address the customer’s Protection

3. A0 is not used in Read Electronic Signature in either x8 or x16 mode. The data is always presented on the lower byte in x16 m ode.
