A write to the One-shot Measurement register address 0Fh initiates a temperature measurement when aSC7611 is in Stop
mode (set by bit 6 of register 09h) and returns to that mode after all three temperature and five voltage measurements are
complete.

The Register Names define the typical input voltage at which the reading is full scale or C0h.
The Voltage Reading registers are updated automatically by the aSC7611 at a minimum frequency of 4Hz. These registers
are read only – a write to these registers has no effect.

If a voltage input either exceeds the value set in the voltage high limit register or falls below the value set in the voltage low
limit register, the corresponding bit will be set automatically by the aSC7611 in the interrupt status registers (41-42h).
Voltages are presented in the registers at of full-scale for the nominal voltage, meaning that at nominal voltage, each input
will be C0h, as shown in Table 3. Note that 3.3V input is Vdd and is not allowed to go below 3.0V during normal operation.
