Abstract
A pulse width of a pulse having a nominal pulse width is modulated in accordance with a digital value to be communicated. The number of clock cycles that the modulated pulse width exceeds the nominal pulse width is counted. Various embodiments use a counter to determine the extent that the modulated pulse exceeds the nominal pulse width. The counter is initialized to a value (P) upon detection of a first edge of the extended pulse. The counter is configured to rollover or is reset when the counter reaches a count of P+M, where M represents the nominal pulse width count. In various embodiments, P is zero. The counter is halted upon detection of a second edge of the extended pulse. The resulting count represents the digital data value.
