Questions answered in these manuals
What are the two configuration modes of the SH69P461/P862/P842/P822/P802/P801 EVB?
The board can operate in ICE mode, where it connects to a motherboard via the ICE interface, or in stand‑alone mode, where a Flash or EPROM stores the program.
From: Sino Wealth SH69P461/P862/P842/P822/P802/P801 EVB Application Notes
How do you select stand‑alone mode on the EVB?
Short JP4 and set S1 to select stand‑alone mode; the on‑board RC oscillator will then provide the system clock.
