1
A0
Active-high A bit 0; A0 is the least-significant bit.
2
A1
Active-high A bit 1.
3
A2
Active-high A bit 2.
4
A3
Active-high A bit 3; A3 is the most-significant bit.
5
B0
Active-high B bit 0; B0 is the least-significant bit.
6
B1
Active-high B bit 1.
7
B2
Active-high B bit 2.
8
B3
Active-high B bit 3; B3 is the most-significant bit.
9
A>B
Active-high final A greater-than B result.
10
A=B
Active-high final A equals B result.
11
A<B
Active-high final A less-than B result.
12
I(A>B)
Active-high lower-word greater-than cascade input.
13
I(A=B)
Active-high lower-word equality cascade input. Tie high for the least-significant or standalone stage.
14
I(A<B)
Active-high lower-word less-than cascade input.
