Function
Turns OFF all ON bits and turns ON all OFF bits in Wd.
Wd Wd: 1 0 and 0 1
Turns OFF all ON bits and turns ON all OFF bits in Wd and Wd+1.
(Wd+1, Wd) (Wd+1, Wd)
Function
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.
Counts the total number of ON bits in the specified word(s).
N words
Counts the number of
ON bits.
