The SH69K20A EVB is used to evaluate the function of the SH69K20A chip for the development of application programs. It contains a SH69V20A chip to evaluate the functions of SH69K20A.
The SH69K20A EVB is an evaluation board used to assess the functions of the SH69K20A chip. It can operate in two configurations: ICE mode, where the board connects to a SH66xx ICE motherboard via the ICE interface, and stand‑alone mode, which uses an external power source and EPROM interface.
The document details programming steps, jumper and switch settings, LED indicators, and power specifications. It includes guidance on assembling programs, loading them into EPROMs, configuring oscillators, and using the reset and watchdog functions.
