Read Identification Page (available only in M95512-DR
devices)
The Identification Page (128 bytes) is an additional page which can be written and (later)
permanently locked in Read-only mode.
Reading this page is achieved with the Read Identification Page instruction (see
The Chip Select signal (S) is first driven low, the bits of the instruction byte and address
bytes are then shifted in, on Serial Data input (D). Address bit A10 must be 0, address bits
[A15:A11] and [A9:A7] are Don't Care, and the data byte pointed to by [A6:A0] is shifted out
on Serial Data output (Q).
If Chip Select (S) continues to be driven low, the internal address register is automatically
incremented, and the byte of data at the new address is shifted out. The number of bytes to
read in the ID page must not exceed the page boundary (e.g.: when reading the ID page
from location 90d, the number of bytes should be less than or equal to 38d, as the ID page
boundary is 128 bytes).
The read cycle is terminated by driving Chip Select (S) high. The rising edge of the Chip
Select (S) signal can occur at any time during the cycle. The first byte addressed can be any
byte within any page.
The instruction is not accepted, and is not executed, if a write cycle is currently in progress.
