INSTRUCTION NAME: TFR (signal transfer)
DESCRIPTION: This instruction selects either the SVA input or the analog value contained in
operand 1, depending on the transfer control status contained in operand 2. When the transfer
control status is 1, the SVA output is the analog value. When the transfer control status is 0, the SVA
output is the SVA input. The SVD input remains unchanged.

OPERAND DESCRIPTIONS:
Second input - The name of the general register or analog loadable function that contains the
analog value.
Signal select - The name of the general register or discrete loadable function that contains the
discrete transfer control status (1 or 0).
Comment - A comment up to 255 characters long.
FUNCTION EQUATIONS:
If transfer control status = 1
Then SVA(out) = analog value
If transfer control status = 0
Then SVA(out) = SVA(in)
SVD(out) = SVD(in)
