LM83_15 Datasheet, PDF (16/22 Pages) Texas Instruments – Triple-Diode Input and Local Digital Temperature Sensor with Two-Wire Interface

1.0 Functional Description (Continued)
D5: T_CRIT mask for Diode 1, when set to 1 a Diode 1 temperature reading that exceeds T_CRIT setpoint will not activate the
T_CRIT_A pin.
D4: T_CRIT mask for Diode 2, when set to 1 a Diode 2 temperature reading that exceeds T_CRIT setpoint will not activate the
T_CRIT_A pin.
D3: T_CRIT mask for Diode 3, when set to 1 a Diode 3 temperature reading that exceeds T_CRIT setpoint will not activate the
T_CRIT_A pin.
D2: T_CRIT mask for Local reading, when set to 1 a Local temperature reading that exceeds T_CRIT setpoint will not activate
the T_CRIT_A pin.
D1: INT active state inversion. When INT Inversion is set to a 1 the active state of the INT output will be a logical high. A low would
then select an active state of a logical low.
D6 and D0: These bits are always set to 0 and reserved for future use. A write of 1 will return a 0 when read.
2.6 LOCAL, DIODE 1, DIODE 2 and DIODE 3 HIGH SETPOINT REGISTERS (LHS, D1RHS, D2RHS and D3RHS)
(Read Address 05h, 07h, 38h, 3Ah /Write Address 0Bh, 0Dh,
50h, 52h):
D7 D6 D5 D4 D3 D2 D1 D0
MSB Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 LSB
D7–D0: HIGH setpoint temperature data. Power up default is LHIGH = RD1HIGH=RD2HIGH=RD3HIGH = 127˚C.
2.7 T_CRIT REGISTER (TCS)
(Read Address 42h/Write Address 5Ah):
D7 D6 D5 D4 D3 D2 D1 D0
MSB Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 LSB
D7–D0: T_CRIT setpoint temperature data. Power up default is T_CRIT = 127˚C.
