Bit 0
16-Bit Signed Integer
LSB
MSB
This data type displays a 16-bit register as a signed Integer (two’s
complement) value. The 16th bit of the register is the sign bit and is set
(1) for a negative and cleared (0) for a positive number. The 16-bit
signed integer values have a range of -32768 to +32767.
Note: This data format may also be scaled to different engineering units.

Bit 15
Range = 0 to +65535
Bit 0
16-Bit Unsigned Integer
LSB
MSB
This data format displays a 16-bit register as an Unsigned Integer value.
It represents a positive number by using the 16th bit as a data bit rather
than a sign bit. The 16-bit Unsigned Integer values have a range of 0 to
+65,535.
Note : This data format may also be scaled to different engineering units.
