each zone are independently configured by the customer using the Access Control Registers. Refer to Appendix H for

additional information on access control.

Note:

Memory maps in this section are for reference and are not intended to accurately illustrate the physical page

length of each User Memory configuration. The physical page length is equal to the maximum number of

bytes that can be written with a standard write command. The Write User Zone command will not write data

across page boundaries; each physical page must be written with a separate command.
