Reads back 0.
This bit is set to 1 when the temperature goes below the T
when the status register is read and/or when the temperature measured goes back above the limit
set in the T
This bit is set to 1 when the temperature goes above the T
when the status register is read and/or when the temperature measured goes back below the limit
set in the T
This bit is set to 1 when the temperature goes above the T
when the status register is read and/or when the temperature measured goes back below the limit
set in the T
This bit goes low when the temperature conversion result is written into the temperature value
register. It is reset to 1 when the temperature value register is read. In one-shot and 1 SPS modes,
this bit is reset after a write to the one-shot bits.

STATUS REGISTER
This 8-bit read-only register (Register Address 0x00) reflects the
status of the overtemperature and undertemperature interrupts
that can cause the CT and INT pins to go active. It also reflects the
status of a temperature conversion operation. The interrupt flags
in this register are reset by a read operation to the status register
and/or when the temperature value returns within the tempera-
ture limits including hysterisis. The RDY bit is reset after a read
from the temperature value register. In one-shot and 1 SPS
modes, the RDY bit is reset after a write to the one-shot bits.
