Description
Rotates "n" bits of the 32-bit data specified by D, including carry flag data, to the left when the trigger turns on.

Carry flag
Content of MSB
When "n" bits with carry flag data are rotated to the left,
− The data in bit position 32-n (nth bit starting from bit position 31) is transferred to special internal
relay R9009 (carry flag).
− "n" bits starting from bit position 31 are shifted out to the left and then carry flag data and the n-1 bits
starting from bit position 31 are shifted into the lower bit positions of the 32-bit data specified by D.
Only the lower eight bits of the 16-bit data "n" are effective.

Upper 8 bits
are invalid
When "n" is specified using K0, the contents of "D+1 and D" and the carry flag do not change.
Precautions during programming
If the specified "n" is a multiple of 33 bits, the data will be the same as that before the operation.
e.g.,n = K33: same operation as n = K0
Flag conditions
・Error flag (R9007):
・Error flag (R9008):
・Carry flag (R9009): Content in the nth bit from MSB (most significant bit) turns on for an instant
