Abstract
An integrated circuit (IC) configurable as transmitter/receiver includes a microcontroller to aid in decoding a pulse width modulated serial dam stream. The microcontroller accomplishes the decoding with the aid of a counter and an external clock signal without the necessity of using interrupts. Edge detection circuitry detects the rising and the rising edge of the incoming data pulse. The external clock signal clocks a counter to determine how many clock signals the incoming pulse corresponds to. The microcontroller polls the counter on the rising edge and the falling edge.
