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 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.
