Even a single cpu can use four frequency sources at once: A crystal that determines the MIPS. The watchdog. A crystal for the real time clock. An RC oscillator that times flash and EEPROM writes. --- Michael Hennebry [email protected] "War is only a hobby." ---- Msg sent via CableONE.net MyMail - http://www.cableone.net _______________________________________________ Simulavr-devel mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/simulavr-devel
