Up to 256 endpoints can be stored in the line-segment data table beginning at
C+1. The following 5 kinds of I/O data can be used:
• 16-bit unsigned BCD data
• 16-bit unsigned binary data
• 16-bit signed binary data (CS1-H/CJ1-H/CJ1M Only)
• 32-bit signed binary data (CS1-H/CJ1-H/CJ1M Only)
• Single-precision floating-point data (CS1-H/CJ1-H/CJ1M Only)
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.)
