ROL(P)
• These instructions rotate the 16-bit binary data in the device specified by (d) to the left by (n) bit(s) (not 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 left within the device range specified by nibble 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.
