4.6 Configuration register
The STTS751 configuration register is read/write and controls the functionality of
temperature measurements. It is located at address 03h. The configuration register bits
function as described below.
Description
MASK1: [bit 7]
0: EVENT
is enabled. Any out-of-limit condition asserts the EVENT pin (active low).
1: EVENT
is disabled.
RUN
/STOP: [bit 6]
0: Device is running in continuous conversion mode.
1: Device is in standby mode drawing minimum power.
The RUN
/STOP bit controls temperature conversions by the ADC. When this bit is 0, the
ADC converts temperatures in continuous mode, at a rate as selected by the Conversion
Rate register (Section 4.7). When the RUN
/STOP bit is 1, the ADC will be in standby mode,
thus reducing current supply significantly.
Note: The device can still be accessed via the SMBus while in standby mode.
When RUN
/STOP is 1 and the one-shot register is written to, the ADC will execute a
temperature measurement and then return to standby mode.
[bit 5]: This bit must always be 0.
RFU: [bit 4] Not used - reserved.
