56F8356 Technical Data, Rev. 13
48 Freescale Semiconductor
Preliminary
on the Data Memory buses and is controlled separately by its own set of banked registers.
The top nine words of the Program Memory Flash are treated as special memory locations. The content of
these words is used to control the operation of the Flash Controller. Because these words are part of the
Flash Memory content, their state is maintained during power-down and reset. During chip initialization,
the content of these memory locations is loaded into Flash Memory control registers, detailed in the Flash
Memory chapter of the 56F8300 Peripheral User Manual. These configuration parameters are located
between $01_FFF7 and $01_FFFF.

Table 4-7 shows the page and sector sizes used within each Flash memory block on the chip.
Note: Data Flash is NOT available in the 56F8156 device.
Please see 56F8300 Peripheral User Manual for additional Flash information.
