These bits select one of the four programmable resolutions for temperature data on the
STTS751 providing resolutions down to 0.0625 °C/LSB. The default resolution is 10 bits,
0.25 °C/LSB.
Conversion resolution
RFU [bits 1 and 0] Not used - reserved.
Conversion rate register
The STTS751 conversion rate register is read/write and controls the number of times the
temperature value will be updated each second.
Conversion rate register
The upper four bits of the register are reserved and default to 0 on power-up. The lower four
bits control the conversion rate as shown in the table below. The power-up default is 1
conversion per second. The current draw is proportional to the conversion rate, and goes up
at higher rates.
