
The bits in D are divided into groups ( n bits as a group), and these
groups are rotated leftwards with a carry flag.

D : Device which is rotated
。
n : Number of bits forming a group

The n
th
bit from the left is transmitted to a carry flag.

Generally, the pulse instructions RCLP and DRCLP are used.

If the operand D is KnM/KnS, Kn in KnM/KnS must be K4 (16 bits) or K8
(32 bits).

If KnM/KnS is used, it is suggested that M device numbers/S device
numbers should start from a number which is a multiple of 16 in the
decimal numeral system, e.g. K4M0 and K4S16 (decimal numeral
system).

SM1066 is the carry flag in an Ox motion subroutine, and SM22 is a
carry flag.

When X0.0 is turned from OFF to ON, the bits in D10 are divided into
groups (four bits as a group), and these groups are rotated leftwards with
a carry flag. (The bit marked with
※
is transmitted to the carry flag.)
