Seamlessly transitions between hardware and software SPI clock; auto sck from 4MHz-488Hz; Using a lot of low level tricks, very elegant code. FDxICSP is not only the world's fastest programmer, but it's also the most sophisticated probably. 488Hz SCK allows the target MCU to be one very low system clock for a ultra-ultra low power advanced application.

Note: measured SCK is always lower than the actual SCK because of the over-head and the fact that SPI is not on all the time.
