Byte Bit Name Settings Description Reset Access
[0] BYTE_COUNT Always reads as 0x06, the number of data bytes that the block read
command should expect to read.
0x6 R
[2:1]
ENERGY_COUNT
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 to access the nontruncated version.
0x0
R
[3] ROLLOVER_COUNT Number of times that the energy count has rolled over, from 0x7FFF to
0x0000. This is a straight 8-bit binary value.
0x0 R
[6:4]
SAMPLE_COUNT
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.
