5. FLASH MEMORY PROGRAMMING
Writing to a flash memory can be performed without removing the memory from the target system (on-board).
Writing is performed by connecting the dedicated flash programmer (Flashpro II) to the host machine and the target
system.
Also, writing to a flash memory can be performed on an adapter for flash memory writing, which is connected
to Flashpro II.
Remark Flashpro II is a product of Naitou Densei Machidaseisakusho Co., Ltd.
