9.1.2

Read Device Identification

There are multiple commands to read information about the device manufacturer, device type, and device features. SPI memories

from different vendors have used different commands and formats for reading information about the memories. The S25FL128S and

S25FL256S devices support the three most common device information commands.

9.1.3

Register Read or Write

There are multiple registers for reporting embedded operation status or controlling device configuration options. There are

commands for reading or writing these registers. Registers contain both volatile and non-volatile bits. Non-volatile bits in registers

are automatically erased and programmed as a single (write) operation.
