FLL - Fill File
Instruction Type: output
The FLL instruction loads elements of a file with either a constant or an
address data value for a given length. The following figure shows how file
instruction data is manipulated. The instruction fills the words of a file
with a source value. It uses no status bits. If you need an enable bit,
program a parallel output that uses a storage address.
This instruction uses the following operands:
•
Source - The source operand is the address of the value or constant
used to fill the destination. The data range for the source is from
-32768 to 32767 (word) or -2,147,483,648 to 2,147,483,647 (long
word), or any IEEE-754 32-bit value.
•
Destination - The starting destination address where the data is
written.
•
Length - The length operand contains the number of elements. The
length can range from 1 to 128 (word), 1 to 64 (long word), or 1 to
42 (3 word element such as counter).

TIP
A constant cannot be used as the source in a timer (T),
counter (C), or control (R) file.
TIP
The source and destination operands must be of the
same file type, unless they are bit (B) and integer (N).
