(2) Sector configuration of 512Kbit flash memory
The 512 Kbit flash memory has the sector configuration illustrated below. The addresses in the illustration are
the upper and lower addresses of each sector.
When accessed from the CPU, SA0 to SA3 are allocated in the FF bank registers, respectively.
* : Programmer addresses correspond to CPU addresses when data is programmed in flash memory by a parallel
programmer. Programmer addresses are used to program/erase data using a general-purpose programmer.
