(2) Sector configuration of flash memory
The flash memory has the sector configuration illustrated below. The addresses in the illustration are the upper
and lower addresses of each sector.
When 512K bits flash memory is accessed from the CPU, SA0 to SA3 are allocated in the FF bank.
When 1024K bits flash memory is accessed from the CPU, SA0 to SA4 are allocated in the FE and FF bank.
* : The writer address is the address corresponding to the CPU address when writing data from a parallel flash
memory writer. Use the writer address when programming or erasing using a general-purpose parallel writer.
