Special data
processing
124 Data search
Searches through data table of n words headed by
(B) for data matching the contents of (A). Stores the
number of matches in (C), and stores the lowest
register address of the matching registers in (C)+1.
5~6 176
125 Push
Pushes the data in (A) into the table of n words
headed by (C), and increments the value of (B) by 1.
5~6 147
126 Pop last
Takes out the data pushed in last to the table of n
words headed by (A) and stores it in (C). Also
decrements the value of (B) by 1.
5 143
127 Pop first
Takes out from the table of n words headed by (A)
the data which was pushed in first, and stores it in
(C). Also decrements the value of (B) by 1.
5 133
147 Flip-flop
When the set input (S) is ON, the instruction sets the
device (A) to ON; when the reset input (R) is ON, it
resets the device (A) to OFF. (Reset takes priority)
2 73
149 Up-down counter
If the enable input (E) is ON, the instruction counts
the number of times the count input (C) has come
ON and stores it in the counter register (A). The
selection of the count direction
(increment/decrement) is made according to the state
of the up/down selection input (U) (see below).
ON: UP count (increment)
OFF: DOWN count (decrement)
