How to check the Flash Version on M16C/62
1.0 Abstract
The following article introduces and shows an example of how to check the internal Flash Version on M16C/62
group device.
2.0 Introduction
The Flash devices of the M16C/62 group have various types of Flash inside. Depending on the exact
typenumber of the microcontroller, different Flash technologies and processes are used. The M16C/62A series
has for example DINOR Flash technology inside, whereas the M16C/62P series utilizes HND Flash
technology. If more than one series is used in a product and the program needs to be updated in the field, it is
required to detect the correct type in order to apply the correct Flash programming algorithm in CPU
programming mode.
Here a method is presented how to do this for any M16C series by a “Flash identification register”.
