When CIO 000000 is ON in the following example, the content of D0100 and
D01001 is incremented by 1 as a BCD value.

When the execution condition is OFF, DECL(095) is not executed. When the ex-
ecution condition is ON, DECL(095) decrements the 8-digit BCD number con-
tained in Wd+1 and Wd, without affecting carry (CY). Wd+1 contains the 10

Wd and Wd+1 must be BCD.
Note Refer to page 101 for general precautions on operand data areas.
ER (A50003): Wd or Wd+1 is not BCD
Content of *DM word is not BCD when set for BCD.
EQ (A50006): The result is 0.
