Sector Configuration Of 2M Bit Flash Memory - Fujitsu F2MC-16LX Hardware Manual

26.2 Sector Configuration of 2M Bit Flash Memory

This section describes the sector configuration of the 2M bit flash memory.
I Sector configuration
Figure 26.2-1 "Sector Configuration of 2M Bit Flash Memory" shows the sector configuration of
the 2M bit flash memory. The figure indicates the upper and lower addresses of each sector.
In accesses from the CPU, SA0 is allocated in the FC bank register, SA1 is allocated in the FD
bank register, SA2 is allocated in the FE bank register, and SA3-6 are allocated in the FF bank
register.
❍ Programmer Address
The programmer address shown in Figure 26.2-1 "Sector Configuration of 2M Bit Flash
Memory" is the address corresponding to the CPU address when data is written to the flash
memory with a parallel programmer. When using a general-purpose programmer for write/erase
operations, this address is used for write/erase operations.
