1.11 POINTER REGISTER (Selects which registers will be
read from or written to):
P0-P1: Register Select:
P3–P7: Must be kept zero.
1.12 TEMPERATURE REGISTER (Read Only):
D0–D6: Undefined.
1.13 CONFIGURATION REGISTER (Read/Write):
Power up default is with all bits “0” (zero).
D0: Shutdown: When set to 1 the LM75 goes to low power shutdown mode.
D1: Comparator/Interrupt mode: 0 is Comparator mode, 1 is Interrupt mode.
D2: O.S. Polarity: 0 is active low, 1 is active high. O.S. is an open-drain output under all conditions.
D3–D4: Fault Queue: Number of faults necessary to detect before setting O.S. output to avoid false tripping due to noise. Faults
are determind at the end of a conversion. See specified temperature conversion time in the electrical tables.
D5–D7: These bits are used for production testing and must be kept zero for normal operation.
