The CMFR is divided into array blocks to allow for independent erase,
address attributes restriction, and protection from program and erase for
each array block. The size of an array block in the CMFR module is fixed
at 16 Kbytes. The total CMFR array is distributed into eight blocks. For
a detailed description of the read page buffer operation see 9.7.2.1 Read
Page Buffers and 9.8.3 Array Read Operation.
