Byte Bit Name Settings Description Reset Access
[0] BYTE_COUNT Always reads as 0x03, the number of data bytes that the block
read command should expect to read.
0x3 R
[3:1]
READ_PIN_EXT
This is the result of the VIN × IOUT calculation that has not been
truncated. Byte 3 is the high byte, Byte 2 is the middle byte, and
Byte 1 is the low byte.

Byte Bit Name Settings Description Reset Access
[0] BYTE_COUNT Always reads as 0x08, the number of data bytes that the block
read command should expect to read.
0x8 R
[3:1] ENERGY_EXT This is the 24-bit energy accumulator in direct format. Byte 3 is
the high byte, Byte 2 is the middle byte, and Byte 1 is the low
byte.
0x0 R
[5:4] ROLLOVER_EXT Number of times that the energy count has rolled over, from
0x7FFF to 0x0000. This is a straight 16-bit binary value. Byte 5 is
the high byte, Byte 4 is the low byte.
0x0 R
[8:6] SAMPLE_COUNT This is the total number of PIN samples acquired and
accumulated in the energy count accumulator. Byte 8 is the high
byte, Byte 7 is the middle byte, and Byte 6 is the low byte.
0x0 R
