Explanation
1. This instructions shift the values of the bits in D by n bits to the left. The instructions fill the vacancies (b
resulting from the shift with 0 and transmit the value of b
SM602.
_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 b10 to
SM602. The instruction fills the values of b0–b5 with zeros after the shift.
