Chapter 27 512 KByte Flash Module (S12XFTM512K3V1)
27.4.2.22 Partition D-Flash Command
The Partition D-Flash command allows the user to allocate sectors within the D-Flash block for
applications and a partition within the buffer RAM for EEPROM access. The D-Flash block consists of
128 sectors with 256 bytes per sector. The Erase All Blocks command must be run prior to launching the
Partition D-Flash command.
Upon clearing CCIF to launch the 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):

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
