PROGRAMMING AND ERASING FLASH MEMORY ON THE MB89F499
1.
Flash Memory
The flash memory is located between 1000
H
and FFFF
H
in the CPU memory map and incorporates a flash
memory interface circuit that allows read access and program access from the CPU to be performed in the same
way as mask ROM. Programming and erasing flash memory is also performed via the flash memory interface
circuit by executing instructions in the CPU. This enables the flash memory to be updated in place under the
control of the internal CPU, providing an efficient method of updating program and data.

Automatic algorithm (Embedded algorithm* : Equivalent to MBM29LV200)
Includes an erase pause and erase restart function
Data polling and toggle bit for detection of program/erase completion
Detection of program/erase completion via CPU interrupt
Compatible with JEDEC-standard commands
Sector Protection (sectors can be combined in any combination)
No. of program/erase cycles : 10,000 (Min)

3.
Procedure for Programming and Erasing Flash Memory
Programming and reading flash memory cannot be performed at the same time. Accordingly, to program or
erase data to the flash memory, the program must first be copied from flash memory to RAM so that programming
can be performed without program access from flash memory.
