The count for each channel is stored in three bytes. To convert the bytes
into the count, multiply each byte as follows:
(Byte 1 * 65536) + (Byte 2 * 256) + Byte 3
The Status byte is configured as:
Bit 0
: Slave counting status (0 = counting, 1 = not counting).
Bit 1
: Overload status. Currently not used.
Bit 2
: HV out of tolerance by 3% (0 = OK, 1 = OOT).
