Operand Data Area
(064)
Wd: Word
ASLL Wd
When the execution condition is OFF, ASLL(064) is not executed. When the ex-
ecution condition is ON, ASLL(064) shifts a 0 into bit 00 of Wd, all bits previously
in Wd and Wd+1 are shifted to the left, and bit 15 of Wd+1 is shifted into CY.
Wd+1
CY
Refer to page 101 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 15 from Wd+1.
EQ (A50006): Content of Wd and Wd+1 are 0 after a shift.
N (A50008): Same status as bit 15 of Wd+1 after shift.
When CIO 000000 is ON in the following example, 0 is shifted into bit 00 of
CIO 0200, the status of all bits within CIO 0200 are shifted left one position, the
status of bit 15 is shifted to bit 00 of CIO 0201, the status of all bits within
CIO 0201 are shifted left one position, and the status of bit 15 is shifted to CY.
