INSTRUCTION NAME: SSLD (signal selector status load)
DESCRIPTION: This instruction is used only with the signal selector PCA. It sets the SVD output
to 0 if the input signal specified by operand 2 is selected by the PCA. If any other input signal is
selected by the PCA, the SVD output is 1. Operand 1 contains the name of the signal selector loop.
This function can be used as the third operand of the OVRD (override) function. The SVA input
remains unchanged.

OPERAND DESCRIPTIONS:
Loop tag - The tag name of the loop that contains the signal selector PCA.
Signal selector input # - The number of the signal selector input that contains the input signal.
There are four possible signal selector inputs; therefore, this number is from 1 to 4. Number 1
corresponds to the SVA input, and numbers 2 through 4 correspond to operands 1 through 3 of the
Signal Selector function.
Comment - A comment up to 255 characters long.
FUNCTION EQUATIONS:
If signal selected = input signal number in operand 2
Then SVD(out) = 0
If signal selected <> input signal number in operand 2
Then SVD(out) = 1
SVA(out) = SVA(in)
