Operand Data Area
(263)
Wd: Word
RRNL Wd
When the execution condition is OFF, RRNL(263) is not executed. When the ex-
ecution condition is ON, RRNL(263) shifts all bits previously in Wd and Wd+1 to
the right, and bit 00 of Wd is shifted into both bit 15 of Wd+1 and into CY.
Wd+1
Refer to page 115 for general precautions on operand data areas.
Content of *DM word is not BCD when set for BCD.
ER (A50003):
CY (A50004): Receives the status of bit 00 from Wd.
EQ (A50006): Content of Wd and Wd+1 are 0 after execution.
N (A50008): Same status as bit 15 of Wd+1 after execution.
When CIO 000000 is ON in the following example, the status of bit 00 of
CIO 0800 is shifted into bit 15 of CIO 0801 and into CY, the status of all bits within
CIO 0801 are shifted right one position, the status of bit 00 is shifted to bit 15 of
CIO 0800, and the status of all bits within CIO 0800 are shifted left one position.
