Abundant M16C middleware (software libraries)
List of M16C software libraries
Performance specification of M16C software libraries (when using the M16C/62)
The software libraries (middleware) normally provided for microprocessors are available for the M16C-family
microcontrollers which essentially are used for controller applications. These software libraries help to reduce
the software development time as well as the number of dedicated external ICs needed.
