Instructions

6.8

Write Identification Page (available only in M95320-DR

devices)

The Identification Page (32 bytes) is an additional page which can be written and (later)

permanently locked in Read-only mode.

Writing this page is achieved with the Write Identification Page instruction (see Table 4). The

Chip Select signal (S) is first driven low. The bits of the instruction byte, address bytes, and

at least one data byte are then shifted in on Serial Data Input (D). Address bit A10 must be

0, upper address bits are Don't Care, the lower address bits [A4:A0] address bits define the

byte address inside the identification page. The instruction sequence is shown in Figure 15.
