Renesas Flash Driver RL78 Type 01 SC version (Code Flash)
Introduction
This document explains Renesas Flash Driver RL78 Type 01 for the RL78/G2x group in the case of using
Smart Configurator(SC). It is a process which builds into a user program the functions for "the code flash
memory driver" included in RFD RL78 Type 01, and it is a method for programming code flash memory using
the attached sample program.
In this document, "Renesas Flash Driver RL78 Type 01” is described to be “RFD RL78 Type 01” or “RFD”.
This document includes the contents in comparison with conventional RFD RL78 Type 01 not using SC. This
document distinguishes and expresses it.
Simple version : Conventional RFD RL78 Type 01 not using SC.
SC version : RFD RL78 Type 01 using "SC" currently explained by this document.
Target Device
The target device group by which the operation for RFD RL78 Type 01 was confirmed.
RL78/G23 group
If this application note is applied to other microcomputers, it is necessary to modify in accordance with the
specification of the microcomputer. And, be sure to evaluate enough.
