Set/Reset Operations
Set/reset operations store the result of logic operation (RLO) formed in the processor. The stored
RLO represents the signal state of the addressed operand. Storage can be dynamic (assignment)
or static (set and reset). Table 8-2 provides an overview of the set/reset operations. Examples
follow the table.

Set
The first time the program is scanned with RLO = "1", signal state
"1" is assigned to the addressed operand. An RLO change does
not affect this status.
Reset
The first time the program is scanned with RLO = "1", signal state
"0" is assigned to the addressed operand. An RLO change does
not affect this status.
Assign
Every time the program is scanned, the current RLO is assigned to
the addressed operand.
