Clearing S:14 before executing the FRD instruction is shown below:
When the input condition I:0/1 is set (1), a BCD value (transferred from a
4-digit thumbwheel switch for example) is moved from word N7:2 into
the math register. Status word S:14 is then cleared to make certain that
unwanted data is not present when the FRD instruction is executed.
