23.2
512K / 1024K Bit Flash Memory Sector Configuration
Figure 23.2-1 and Figure 23.2-2 and shows the sector configuration in the 512K bit flash
memory. The address indicated in Figure 23.2-1 and Figure 23.2-2 is classified into the
upper address and lower address of each sector.
■ Sector Configuration
When accessing the 512Kbit flash memory from the CPU, four sector addresses, SA0 to SA3, are allocated
in the FF bank register.
When accessing the 1024Kbit flash memory from the CPU, five sector addresses, SA0 to SA4, are
allocated in the FE and FF bank register.
*: Writer address
The writer address is equivalent to the CPU address when writing the data to the flash memory using the
parallel writer. If the write/delete operation is executed using the general-purpose writer, the write/delete
operation is executed using this address.
