RA8917
Version 1.0
8-Bit Micro-Controller
Development
The RA8917 support the ISP (In-System Programming) and ISD (In-System Debugging) functions for customer to
develop their system. Users can download their programs as well as data from a PC host to the external Flash
ROM.
-ISP/ISD Mode is entered when the MONITOR# pin having been pulled down to ground voltage level. The
on-chip Monitor program together with RAiO’s ICE (RICE-2000) Utility Program running on a PC will be executed
to support ICE debugging and ISP download of user programs from the PC Host.

-User Mode is entered when the MONITOR# pin has been pulled up to logic high voltage level. User application
programs can be executed only in this mode. The end-user can download the application program or data from
the customer’s website through the PC interface. Because the program/data was stored in the flash so the
application device of customer (such as speech toy) will operate independent that after disconnect with the PC.

RICE-2000 (RICE for short) is a full-completed environment developed by RAiO especially for RA89XX series.
The major reason for developing RICE is give fully convenience to program designers who are using RA89XX IC,
and let them enjoy consistent and friendly design environment at planning, designing and debugging. In RICE
environment, it saves a great deal of developing time by not only providing Editor for users to do direct coding, but
also providing many Hot-Key functions for users to do direct compiling, linking, and downloading. Since
RA89XX series carry 8-bit micro-processor and a framework of ISP (In-System-Programming), ISD (In-System
Debugging), then this simple and reliable environment of RICE can let program designers to proceed design and
debug in Real Chip. Moreover, the mass-production ICs are ready for clients to do planning and designing directly
without diverse traits happened between developing time and mass production period.
In the meanwhile, in order to support integrated speech interface, RICE provides a solution of 32K-bps ADPCM
for programmers to easily combine programs and speech files. If you want to have more information and
program design skills of RA8917, please refer to the user manual of RICE-2000.
