Function
DROL
(1) The 32-bit data of the device designated at
ON or OFF depending on its status prior to the execution of the DROL instruction.
Carry flag
(SM700)
(2) When a bit device is designated for
The number of bits by which a rotation is executed is the remainder of n/(specified number of bits).
For example, when n
rotated 7 bits.
(3) Specify any of 0 to 31 as n. If the value specified as n is 32 or greater, the remainder of n/32 is used for rotation. For
example, when n 34, the data is rotated 2 bits to the left since the remainder of 34/32
DRCL
(1) Rotates 32-bit data of the device designated by
OFF depending on its status prior to the execution of the DRCL instruction.

(2) When a bit device is designated for
The number of bits by which a rotation is executed is the remainder of n/(specified number of bits).
For example, when n
rotated 7 bits.
(3) Specify any of 0 to 31 as n. If the value specified as n is 32 or greater, the remainder of n/32 is used for rotation. For
example, when n 34, the data is rotated 2 bits to the left since the remainder of 34/32
