specified words is incremented only when the execution condition has gone
from OFF to ON.
The Equals Flag will be turned ON if the result is 0000 0000, the Carry Flag
will be turned ON when a digit changes from F to 0, and the Negative Flag will
be turned ON if bit 15 of Wd+1 is ON in the result.
Both the Equals Flag and the Carry Flag will be turned ON when the content
of changes from FFFF FFFF to 0000 0000.

Examples
Operation of ++L(591)
In the following example, the 8-digit hexadecimal content of D00101 and
D00100 will be incremented by 1 every cycle as long as CIO 000000 is ON.
Operation of @++L(591)
The up-differentiated variation is used in the following example, so the content
of D00101 and D00100 will be incremented by 1 only when CIO 000000 has
gone from OFF to ON.
