32.15.2.5 Explanation of the ROR and RORP Instructions
When the ROR or RORP instruction is executed, the S1 bits are
rotated to the right S2 number of bits. One bit rotated, the
information of the bottom-most bit (the least significant bit) is
stored in the topmost empty bit.
The result is stored in D1. The ROR and RORP instructions always
pass power. When using the ROR and RORP instructions, an error will
occur if the variables specified in operands S1 and D1 are not the
same type. Designate the same variable type in operands S1 and
D1.
Refer to the following for specifying a constant.
Specify the address to rotate
Specifies the number of bits to rotate.
Specifies the address to store the rotation
result.
For example, when 1 bit is rotated to the
right
When operand D1 is an integer variable
When operand D1 is an integer variable and
you want to input hexadecimal values in operands S1 and S2
When 0x (zero and lower case "x") is input, the following values
become hexadecimal values.
Use the same format when rotating data in a specified array
(integer variable array) and when specifying an array element.
An error will occur if the formats are different.
If the S1 and D1 arrays are the same size, S1 is treated like a
single giant integer. Bits are rotated from one element to the next
element.
Bits are rotated from one element to the next. The entire array
is rotated, not just bits in each element. Specify S2 as 0 or
higher, up to (32 x Array Size -1).
If both S1 and D1 are not arrays, 32 bits are shifted. For S2,
specify a value between 0 and 31.
