Notes
¥ The instruction list contains the basic instructions in the S1C17 instruction set and the extended instructions (s... and x..., except for xor).
¥ "Italic basic instructions" indicate that the upper compatible extended instructions are provided.
Bit Field
(X): Bit X of data.
(X:Y): A bit field from bit X to bit Y.
{X, Y ··· }: Indicates a bit (data) configuration.
Functions
