Analog features include a multi-channel 8-bit A/D converter function. Two extremely flexible Timer/Event Counters providing functions for timing, event counting and pulse width measurement functions. Protective features such as an internal Watchdog Timer and Low Voltage Reset coupled with excellent noise immunity and ESD protection ensure that reliable operation is maintained in hostile electrical environments. A full choice of internal high and low speed oscillators are provided and the two fully integrated system oscillators require no external ponents for their implementation. The ability to operate and switch dynamically between a range of operating modes using different...
