F2MC-16LX/FX, Softune

embOS for Spansion F2MC-16LX and F2MC-16FX supports all CPUs with F2MC-16LX or F2MC-16FX core. It was developed for and with Spansion's Softune compiler and supports all memory models offered by this compiler. It comes with easy to use workspace and start project for Softune workbench. Software development with debugger, ROM-Monitor and Softune simulator is supported.

Since version 3.22a, fast interrupts with zero latency are supported for embOS F2MC-16LX and F2MC-16FX.
