Left-justified unsigned voltage measurement. To calculate the supply voltage, simply convert the hexadecimal
result into decimal and then multiply it by the LSB as shown in the Analog Voltage Monitoring Characteristics
electrical characteristics table. The lower 3 bits always return zero.

BIT 0
These registers are the left- justified digital 10-bit value used for their associated DAC output. The lower 6 bits
have no effect on device operation. At POR these registers are updated to the EEPROM value DAC POR. When
the EN bit in DAC POR is set, this register is updated at the end of each temperature conversion, with the calcu-
lated result of values recalled from LUT and OFFSET LUT pointed to by TINDEX.
