4Ć99FST Configuration

Original Ć June 1990 CE4.2:CL6211

IFF IFF

INSTRUCTION NAME: IFF (if false transfer)

DESCRIPTION: This instruction transfers the SVA and SVD outputs to the function identified by

the label name contained in operand 2 based on the status of operand 1. If the status of operand 1

is 0, the transfer will take place. If the status of operand 1 is 1, no transfer will take place, and the

SVA and SVD outputs go to the next function in the FST. Restrictions on the use of IFF are the same

as for the GOTO instruction. The SVA and SVD inputs remain unchanged.

CONFIGURATION FORMAT: IFF (

OPERAND DESCRIPTIONS:

Trip transfer status - The name of the general register or discrete loadable function that contains

the transfer status (1 or 0).

Label name - The label that identifies where FST execution is to be transferred to. Label names

can be any string up to 12 characters consisting of characters, numbers, hyphens and

underscores.

Comment - A comment up to 255 characters long.

FUNCTION EQUATIONS:

SVA(out) = SVA(in)

SVD(out) = SVD(in)

If Trip transfer status = 1

Then no transfer

If Trip transfer status = 0

Then transfer execution to label name
