Description
Always reads as 0000.
Input voltage from the SENSE+ pin measurement, expressed in ADC codes.
Description
Always reads as 0000.
Output voltage from the VOUT pin measurement, expressed in ADC codes.
Description
Always reads as 0000.
Output current from the measurement through the sense resistor, expressed in ADC codes.
Description
Always reads as 0.
Input power from the VIN × IOUT calculation.
Description
Always reads as 0010, PMBus Specification Part I, Revision 1.2.
Always reads as 0010, PMBus Specification Part II, Revision 1.2.
Description
Always reads as 0x06, the number of data bytes that the block read command
should expect to read.
Energy accumulator value in direct format. Byte 2 is the high byte, and Byte 1 is the
low byte. Internally, the energy accumulator is a 24-bit value, but only the most
significant 16 bits are returned with this command. Use the READ_EIN_EXT
command to access the nontruncated version.
Number of times that the energy count has rolled over from 0x7FFF to 0x0000. This
is a straight 8-bit binary value.
This is the total number of PIN samples acquired and accumulated in the energy
count accumulator. Byte 6 is the high byte, Byte 5 is the middle byte, and Byte 4 is
the low byte. This is a straight 24-bit binary value.
