Instruction Set Quick Reference
Description
When the input conditions are true, take the opposite sign of
the Source (N7:3) and store the result in the Destination
(N7:12). This instruction turns positive values into negative
values and negative values into positive values.
Status
Description
Bit
C sets if the operation generates a carry;
otherwise resets
V sets if overflow is generated;
otherwise resets
Z sets if the result is zero;
otherwise resets
S sets if the result is negative;
otherwise resets
When input conditions go true, take the sine of the value in
F8:11 and store the result in F8:12.
Status

Bit
C always resets
V sets if overflow is generated;
otherwise resets
Z sets if the result is zero;
otherwise resets
S
sets if the result is negative;
otherwise resets
When the input conditions are true, take the square root of the
Source (N7:3) and store the result in the Destination (N7:12).
