The D-Flash user partition will start at global address 0x10_0000. The buffer RAM EEE partition will end
at global address 0x13_FFFF. After the Partition D-Flash operation has completed, the CCIF flag will set.
Running the Partition D-Flash command a second time will result in the ACCERR bit within the FSTAT
register being set. The data value written corresponds to the number of 256 byte sectors allocated for either
direct D-Flash access (DFPART) or buffer RAM EEE access (ERPART).
