Description
Shifts n bits of the 32-bit area specified by D to the left (to the higher bit position) when the trigger turns on.
[n bits]

CY
The data in the nth
bit is transferred to
R9009 (carry flag).
When the n bits are shifted to the left,
− The n bits starting from bit position 0 are filled with 0s.
− The data in the nth bit is transferred to special internal relay R9009 (carry flag).
