Command Reference
8.8.2 Bit Left Shift (SFL)
(1) Overview
The SFL command shifts a bit string designated by the leading bit number and bit width the specified number of
shifts to the left.
(2) Format
(3) Programming Examples
SFL command programming examples are shown below.
Examples: Ten bits with MB00100A (bit A of MW00100) as the leading bit are shifted five bits to the left.
With the SFL command, if the number of shifts is greater than the bit width, all data with the specified bit width will be set
to 0.
