Protection Register Map
Reading the Protection Registers
The Protection Registers can be read from any address. To read the Protection Register, first issue
the Read Device Identifier command at any address to place the device in the Read Device
Identifier state (see
using the address offset corresponding to the register to be read.
Information” on page 77
Register data is read 16 bits at a time.
Programming the Protection Registers
To program any of the Protection Registers, first issue the Program Protection Register command
at the parameter’s base address plus the offset to the desired Protection Register (see
