SYSTEM DEVELOPMENT

1. Software (SC8521)

A PC program is provided that enables the user to fill in system and command codes for each keys number in

each bank. This program converts the input data into a ROM code-file needed to produce the metal mask and to

program an EPROM to be used in the hardware emulator.

2. Hardware

An emulator is available that functionally emulates the IC. An EPROM with the ROM code information is

inserted into the emulator to produce the required remote control codes corresponding to the keys in the prototype

device.
