8.8 Data Operations
This section describes the data operation commands that are used to shift, transfer, and initialize data.
8.8.1 Bit Right Shift (SFR)
(1) Overview
The SFR command shifts a bit string designated by the leading bit number and bit width the specified number of
shifts to the right.
(2) Format
(3) Programming Examples
SFR command programming examples are shown below.
Example: Five bits with MB001005 (bit 5 of MW00100) as the leading bit are shifted three bits to the right.
With the SFR command, if the number of shifts is greater than the bit width, all data with the specified bit width will be set
to 0.
