NOTE: DEPENDING ON ITS INTERNAL STATE, A 1-Wire SLAVE DEVICE TRANSMITS DATA TO ITS MASTER (e.g. THE DS2482-100). WHEN RESPONDING WITH A 0,
A 1-Wire SLAVE STARTS PULLING THE LINE LOW DURING t
STARTS RISING AGAIN. WHEN RESPONDING WITH A 1, A 1-Wire SLAVE DOES NOT HOLD THE LINE LOW AT ALL, AND THE VOLTAGE STARTS RISING AS SOON AS t
IS OVER. 1-Wire DEVICE DATA SHEETS USE THE TERM t
SPECIFICATIONS AND CANNOT BE DISTINGUISHED FROM EACH OTHER.
