INSTRUCTION NAME: FFS (flip-flop set)
DESCRIPTION: This instruction sets the SVD output to the last SVD output if both the SVD input
and the discrete value contained in operand 1 are 0. The SVD output is 1 if the SVD input (SET) is 1
and the discrete value contained in operand 1 (RESET) is 0. The SVD output is 0 if the SVD input
(SET) is 0 and the discrete value contained in operand 1 (RESET) is 1. The SVD output is 1 if both
the SVD input and the discrete value are 1. The SVA input remains unchanged.
