ONE-SHOT MODE
When one-shot mode is enabled, the ADT7310 immediately
completes a conversion and then goes into shutdown mode. The
one-shot mode is useful when one of the circuit design priorities is
to reduce power consumption.
To enable one-shot mode, set Bits[6:5] of the configuration
register (Register Address 0x01) to 01.
After writing to the operation mode bits, wait at least 240 ms
before reading back the temperature from the temperature value
register. This delay ensures that the ADT7310 has adequate time
to power up and complete a conversion.
To obtain an updated temperature conversion, reset Bits[6:5] of the
configuration register (Register Address 0x01) to 01.
1 SPS MODE
In this mode, the part performs one measurement per second.
A conversion takes only 60 ms, and it remains in the idle state
for the remaining 940 ms period. This mode is enabled by
writing 1 to Bit 6 and 0 to Bit 5 of the configuration register
(Register Address 0x01).
