Upon clearing CCIF to launch the Full Partition D-Flash command, the following actions are taken to
define a partition within the D-Flash block for direct access (DFPART) and a partition within the buffer
RAM for EEE use (ERPART):
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 Full Partition D-Flash operation has completed, the CCIF flag will
set.
Running the Full Partition D-Flash command a second time will result in the previous partition values and
the entire D-Flash memory being erased. 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).

Validate the DFPART and ERPART values provided:
— DFPART <= 128 (maximum number of 256 byte sectors in D-Flash block)
— ERPART <= 16 (maximum number of 256 byte sectors in buffer RAM)
— If ERPART > 0, 128 - DFPART >= 12 (minimum number of 256 byte sectors in the D-Flash
— If ERPART > 0, ((128-DFPART)/ERPART) >= 8 (minimum ratio of D-Flash EEE space to
