Word (16 Bits): MODBUS register
The Bit [x: y] notation shown in the table indicates all bits from x to y. For example Bit [2:1] indicates
bit 2 and bit 1, and serves to illustrate the meaning of the various united combinations of the values
of the two bits. On the other hand, the symbol * indicates the default value.
