Conversion rates
The user must program the conversion rate and resolution bits (Tres1:Tres0 in the
configuration register, address 03h) to be consistent with this table. For a sampling rate of
32 conversions per second, the maximum resolution is 10 bits. For 16 conversions per
second, the maximum is 11 bits.
One-shot register
The STTS751 can be configured to perform a single temperature conversion on demand.
When the device is placed in standby mode (by setting RUN/STOP to 1 in the configuration
register) a write to the one-shot register will invoke a temperature conversion. The device
will set the busy bit while the conversion is in progress. The conversion is complete when
the busy bit is cleared. The STTS751 returns to standby mode upon completion of the
conversion.
The one-shot register is write-only and is located at address 0Fh. The value written to
invoke the one-shot conversion is a don't care. The device responds only to the write at
address 0Fh and ignores the value written.
Writes to the one-shot register will be ignored when the STTS751 is in continuous
conversion mode (ie. when RUN/STOP=0).
