5. Temperature Data Read Mode
Note 1: The temperature sensor is triggered on the rising edge of STB. Allow a period of length t to elapse so that
(V.P = = = = 18 V, W/R = = = = “H”, DI1 = = = = “L”, DI2 = = = = “H”, DI3 = = = = “L”, DI4 = = = = “L”, DI5 = = = = “H”)
W/R = H and STB = H) proceeds to overwrite the entire E

During Overwrite Mode, DOUT is High-Impedance.
