Design and Implementation of In-Circuit Programming for Flash Memory in HCS08 MCU Family
On the basis of analysis of the characteristics of flash memory in HCS08 MCU family, how to perform program and erase operations are demonstrated during in-circuit programming of flash memory in HCS08 MCU family. In order to solve the unstable problem during in-circuit programming of flash memory, three methods are put forward. After studying on the features of the three methods, the implementation of the methods is given. During the debugging, MC9S08AW60 MCU is chose to verify the feasibility of the methods, and the experiment experience is supplied. The paper plays an importance role in in-circuit programming of flash memory in HCS08 MCU family.
