7.2 Rotation instruction 7.2.2 ROL, ROLP, RCL, RCLP
: Head number of the devices to rotate (BIN 16 bits)
n : Number of rotations (0 to 15) (BIN 32 bits)
Function
ROL
(1) Rotates the 16-bit data of the device designated at , not including the carry flag, n-bits to the left.
The carry flag turns ON or OFF depending on its status prior to the execution of ROL instruction .
(2) When a bit device is designated for , a rotation is performed within the device range specified by digit specification.
The number of bits by which a rotation is executed is the remainder of n/(specified number of bits).
For example, when n 15 and (specified number of bits) 12 bits, the remainder of 15/12 1 is "3", and the data is
rotated 3 bits.
(3) Specify any of 0 to 15 as n.
If the value specified as n is 16 or greater, the remainder of n / 16 is used for rotation.
For example, when n 18, the data is rotated 2 bits to the left since the remainder of 18/16 1 is "2".
