Explanation
1. This instructions shift the values of the bits in D by n bits to the right. The 16-bit instruction fills the vacancies (b
b ) resulting from the shift with 0 and the 32-bit instruction fills the vacancies (b
15-n+1
shift with 0. The value of b
_6
2. The operand n must be between 1–16 for 16-bit instructions and the operand n must be between 1–32 for 32-bit
instructions.
3. In general, the SFRP/DSFRP pulse instruction is used more commonly.
4. Only the DSFR/DSFRP instruction (32-bit instructions) can use the 32-bit counter (high counter) but not the device
E.
Example
When X0.0 is ON, the instruction shifts the values of b0–b15 in D0 by 6 bits to the right, and transmits the value of b5 to
SM602. The instruction clears the values of b10–b15 to zero after the shift.
The shift of the values of the bits to the right during a scan is shown below.
