13.2.1
Reading the Protection Registers
The Protection Registers can be read from within any partition’s address space. To read
the Protection Register, first issue the Read Device Identifier command at any
partitions’ address to place that partition in the Read Device Identifier state (see
Section 9.2, “Device Commands” on page 40). Next, perform a read operation at that
partition’s base address plus the address offset corresponding to the register to be
the Protection Registers and Lock Registers. Register data is read 16 bits at a time.
Note:
If a program or erase operation occurs within the device while it is reading a Protection
Register, certain restrictions may apply. See Table 21, “Simultaneous Operation
