Processing
Example 1) Operation unit: 16 bits (US)
Output bit 12 of the pre-operation data to CY. (Output bit 0 of the post-operation data to CY)
Example 2) Operation unit: 32 bits (UL)
Output bit 24 of the pre-operation data to CY. (Output bit 0 of the post-operation data to CY)

Name Description
SR7
SR8
(ER)
To be set in the case of out-of-range in indirect access (index modification).
SR9
(CY)
(Bit length of the operation unit - rotation amount) bits of the pre-operation data are output.
When the operation unit is 16 bits (US), if [n] is either 0 or a multiple of 16, the rotation
amount is regarded as 0, and no change occurs.
When the operation unit is 32 bits (UL), if [n] is either 0 or a multiple of 32, the rotation
amount is regarded as 0, and no change occurs.
