RL78 Tips and Tricks

Here are the frequently asked RL78 questions and answers to them.  There are a few tips and tricks also to help your journey with your development.  

RL78 Flash Self Programming Considerations

Some quick tips to help you with Flash Self-programming RL78 MCUs.  

How can a binary file exceeding 64KB be linked to code flash when developing with CC-RL?

The description in one Knowledge Base article states that with the use of the -binary option in Linker, binary files within 64KB can be assigned to the address range of 0-0x0FFFF.

However, how can binary files larger than 64KB be linked into the project?

Link Executables of Any Size

This tip shows you how to link executable files of any size.  This could be needed as RL78 MCUs several addressing modes e.g., SFR addressign, register addressing, short direct addressing and direct addressing to name a few.  RL78 MCUs utilize ES and CS registers to expand the addressign spaces to 20 bits.
