8 APPLICATION INSTRUCTION
8.1 Rotation Instruction
373
8
■
RCR(P)
• These instructions rotate the 16-bit binary data in the device specified by (d) to the right by (n) bit(s) (including the carry
flag). The carry flag is on or off depending on the status prior to the execution of the instruction.
• When (d) is a bit device, bits are rotated to the right within the device range specified by digit specification. The number of
bits actually to be rotated is the remainder of (n)
(specified number of bits). For example, when (n) is 15 and the specified
number of bits is 12, 3 bits are rotated because 15 divided by 12 equals 1 with a remainder of 3.
• Specify any value between 0 and 15 for (n). If a value 16 or bigger is specified, bits are rotated by the remainder value of
n
16. For example, when (n) is 18, 2 bits are rotated because 18 divided by 16 equals 1 with a remainder of 2.
Precautions
• Do not set a negative value to the number of bits to be rotated (n).
• In the case of continuous operation type instructions (ROR and RCR), note that shift and rotation are executed in every
scan time (operation cycle).
Operation error
There is no operation error.
