Table 6: Status Register Bit
Read Electronic Signature
The device contains a Manufacturer Code and Device Code. To read these codes two steps are required:
1. first use one Bus Write cycle to issue the Read Electronic Signature command (90h)
2. then subsequent Bus Read operations will read the Manufacturer Code and the Device Code until another command
is issued.
Refer to Table, Read Electronic Signature for information on the addresses.
Automatic Page 0 Read at Power-Up
Automatic Page 0 Read at Power-Up is an option available on all devices belonging to the NAND Flash 528 Byte/264
Word Page family. It allows the microcontroller to directly download boot code from page 0, without requiring any
command or address input sequence. The Automatic Page 0 Read option is particularly suited for applications that
boot from the NAND.
Devices delivered with Automatic Page 0 Read at Power-Up can have the Sequential Row Read option either enabled
or disabled.
