6.6.64 Temperature (T) – Page 16, Address 27

Default = 0x00 0000

T contains results from the on-chip temperature measurement.

By default, T uses the Celsius scale, and is a two's complement value in the range of -128.0

value128.0

(°C), with the binary point to the right of bit 16. Negative values are not used.

T can be rescaled by the application using the TGAIN and TOFF registers.

6.6.65 Total Active Power (PSUM) – Page 16, Address 29

Default = 0x00 0000

PSUM =P1AVG+P2AVG if MCFG[1:0] = 01

PSUM =P1AVG or P2AVG if MCFG[1:0] = 00

This is a two's complement value in the range of -1.0

value1.0, with the binary point to the right of the MSB.

6.6.66 Total Apparent Power (SSUM) – Page 16, Address 30

Default = 0x00 0000

SSUM = S1+S2 if MCFG[1:0] = 01

SSUM = S1 or S2 if MCFG[1:0] = 00

This is an unsigned value in the range of 0

value1.0, with the binary point to the right of the MSB.

6.6.67 Total Reactive Power (QSUM) – Page 16, Address 31

Default = 0x00 0000

QSUM =Q1AVG+Q2AVG if MCFG[1:0] = 01

QSUM =Q1AVG or Q2AVG if MCFG[1:0] = 00

This is a two's complement value in the range of -1.0

value1.0, with the binary point to the right of the MSB.
