Function
Operation of the Linear Extrapolation Function
APR(069) processes the input data specified in S with the following equation and the line-segment data
(X , Y ) specified in the table beginning at C+1. The result is output to the destination word(s) specified
n n
with D.
1. For S < X
0
Converted value = Y
≤ S ≤ X
2. For X
0
Converted value = Y
3. X < S
max
Converted value = Y
Up to 256 endpoints can be stored in the line-segment data table beginning at C+1.

P_ER • ON if C is a constant greater than 0001.
• ON if C is a word address but the X coordinates are not in ascending order (X
• ON if C is a word address and bits 9, 11, and 15 of C indicate BCD input, but S is not BCD.
• ON if C is a word address and bit 9 of C indicates floating-point data, but S is a one-word constant.
• ON if C is 0000 or 0001 but S is not BCD between 0000 and 0900.
• OFF in all other cases.
P_EQ • ON if the result is 0.
• OFF in all other cases.
P_N • ON if bit 15 of R is ON.
• OFF in all other cases.
