ADT7320
ONE-SHOT MODE
Setting Bit 5 to 0 and Bit 6 to 1 of the configuration register
(Register Address 0x01) enables the one-shot mode. When
this mode is enabled, the ADT7320 immediately completes a
conversion and then goes into shutdown mode.
Wait for a minimum of 240 ms after writing to the one-shot
bits before reading back the temperature from the temperature
value register. This time ensures that the ADT7320 has time to
power up and complete a conversion.
The one-shot mode is useful when one of the circuit design
priorities is to reduce power consumption.

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 5 and 0 to Bit 6 of the configuration register
(Register Address 0x01).
