4.5 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.
T
HIGH
: [6] Bit = 1 indicates temperature high limit has been exceeded (T
A
> high limit).
T
HIGH
is cleared when the status register is read, provided the condition no longer exists.
T
LOW
: [5] Bit = 1 indicates the is at or below the low limit (T
A
≤ low limit). T
LOW
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.
