Figure 43 illustrates the periodic biasing scheme used for measuring the TS state. The TS_READ signal enables
the TS bias voltage for 24ms. During this period the TS comparators are read (each comparator has a 10 ms
deglitch) and appropriate action is taken based on the temperature measurement. After this 24ms period has
elapsed, the TS_READ signal goes low, which causes the TS-Bias pin to become high impedance. During the
next 35ms (priority packet period) or 235ms (standard packet period), the TS voltage is monitored and compared
to 100mV. If the TS voltage is greater than 100mV then a secondary device is driving the TS/CTRL pin and a
CTRL = ‘1’ is detected.
