PROGRAMMING AND ERASING FLASH MEMORY ON THE MB89F538
1.
Flash Memory
The flash memory is located between 4000
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 CPU, providing an efficient method of updating program and data.

Procedure for Programming and Erasing Flash Memory
Programming and reading flash memory cannot be performed at the same time. Accordingly, to program or
erase 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.

* : Programmer address
The programmer address is the address to be used instead of the CPU address when programming data from
a parallel flash memory programmer. Use the programmer address on programming or erasing using a general-
purpose parallel programmer.
