Setting the Data Format in Control Word C
• 16-bit Unsigned BCD Data
The input data and/or the output data can be 16-bit unsigned BCD data.
Also, the linear extrapolation function can be set to operate on the value
specified in S directly or on X
m
–S. (X
m
is the maximum value of X in the
line-segment data.)
• 16-bit Unsigned Binary Data
The input data and/or the output data can be 16-bit unsigned binary data.
Also, the linear extrapolation function can be set to operate on the value
specified in S directly or on X
m
–S. (X
m
is the maximum value of X in the
line-segment data.)
• 16-bit Signed Binary Data
