INSTRUCTION NAME: OR (logical OR)
DESCRIPTION: This instruction performs a logical OR of the SVD input and the discrete value
contained in operand 1. If both the SVD input and the discrete value are 0, then the SVD output is 0.
When either the SVD input or the discrete value, or both, are 1, then the SVD output is 1. The SVA
input remains unchanged.

OPERAND DESCRIPTIONS:
Second Input - The name of the general register or discrete loadable function that contains the
discrete value.
Comment - A comment up to 255 characters long.
