Turns OFF all ON bits and turns ON all OFF bits in Wd.
Wd → Wd: 1 → 0 and 0 → 1
Wd
Turns OFF all ON bits and turns ON all OFF bits in Wd and Wd+1.
(Wd+1, Wd) → (Wd+1, Wd)
Wd
Computes the square root of the 32-bit binary content of the specified
words and outputs the integer portion of the result to the specified
result word.

Binary data (32 bits)
Computes the square root of an 8-digit BCD number and outputs the
integer portion of the result to the specified result word.
S

BCD data (8 digits)
Calculates the sine, cosine, or a linear extrapolation of the source data.
The linear extrapolation function allows any relationship between X and
Y to be approximated with line segments.
