Status register

The STTS751 status register is read-only and located at address 01h. The various status

bits function as described below.

Busy: [7] Bit =1 when a temperature conversion is in progress.

THIGH: [6] Bit = 1 indicates temperature high limit has been exceeded (TA > high limit).

THIGH is cleared when the status register is read, provided the condition no longer exists.

TLOW: [5] Bit = 1 indicates the is at or below the low limit (TA ≤ low limit). TLOW is cleared

when the status register is read, provided the condition no longer exists.

RFU: [4:1] Not used - reserved.

THRM: [0] Bit = 1 indicates the measured temperature has crossed the Therm limit. The

THRM bit will go low when the temperature falls below the Therm limit minus the Therm

Hysteresis. When the THRM bit is high, the Addr/Therm output will be asserted low.
