13 DIFU DIFFERENTIATE UP Turns ON the designated bit for one cycle on the rising
edge of the input signal.
151
14 DIFD DIFFERENTIATE
DOWN
Turns ON the bit for one cycle on the trailing edge. 151
15 TIMH HIGH-SPEED TIMER A high-speed, ON-delay (decrementing) timer. 164
(@)16 WSFT WORD SHIFT Shifts data between starting and ending words in word
units, writing zeros into starting word.
178
17 to 19 For expansion instructions.
20 CMP COMPARE Compares the contents of two words and outputs result to
GR, EQ, and LE Flags.
193
(@)21 MOV MOVE Copies source data (word or constant) to destination word. 180
(@)22 MVN MOVE NOT Inverts source data (word or constant) and then copies it to
destination word.
180
(@)23 BIN BCD TO BINARY Converts four-digit, BCD data in source word into 16-bit
binary data, and outputs converted data to result word.
204
(@)24 BCD BINARY TO BCD Converts binary data in source word into BCD, and outputs
converted data to result word.
205
(@)25 ASL ARITHMETIC SHIFT
LEFT
Shifts each bit in single word of data one bit to left, with CY. 175
(@)26 ASR ARITHMETIC SHIFT
RIGHT
Shifts each bit in single word of data one bit to right, with
CY.
175
(@)27 ROL ROTATE LEFT Rotates bits in single word of data one bit to left, with CY. 176
(@)28 ROR ROTATE RIGHT Rotates bits in single word of data one bit to right, with CY. 176
(@)29 COM COMPLEMENT Inverts bit status of one word of data. 275
(@)30 ADD BCD ADD Adds two four-digit BCD values and content of CY, and
outputs result to specified result word.
229
(@)31 SUB BCD SUBTRACT Subtracts a four-digit BCD value and CY from another
four-digit BCD value and outputs result to the result word.
231
(@)32 MUL BCD MULTIPLY Multiplies two four-digit BCD values and outputs result to
specified result words.
235
(@)33 DIV BCD DIVIDE Divides four-digit BCD dividend by four-digit BCD divisor
and outputs result to specified result words.
236
(@)34 ANDW LOGICAL AND Logically ANDs two 16-bit input words and sets corre-
sponding bit in result word if corresponding bits in input
words are both ON.
276
(@)35 ORW LOGICAL OR Logically ORs two 16-bit input words and sets correspond-
ing bit in result word if one or both of corresponding bits in
input data are ON.
277
(@)36 XORW EXCLUSIVE OR Exclusively ORs two 16-bit input words and sets bit in re-
sult word when corresponding bits in input words differ in
status.
278
(@)37 XNRW EXCLUSIVE NOR Exclusively NORs two 16-bit input words and sets bit in
result word when corresponding bits in input words are
same in status.
279
(@)38 INC BCD INCREMENT Increments four-digit BCD word by one. 228
(@)39 DEC BCD DECREMENT Decrements four-digit BCD word by one. 228
(@)40 STC SET CARRY Sets carry flag (i.e., turns CY ON). 229
(@)41 CLC CLEAR CARRY Clears carry flag (i.e., turns CY OFF). 229
45 TRSM TRACE MEMORY
SAMPLE
Initiates data tracing. 302
(@)46 MSG MESSAGE Displays a 16-character message on the Programming
Console display.
303
47 & 48 For expansion instructions.
(@)50 ADB BINARY ADD Adds two four-digit hexadecimal values and content of CY,
and outputs result to specified result word.
243
(@)51 SBB BINARY SUBTRACT Subtracts a four-digit hexadecimal value and CY from
another four-digit hexadecimal value and outputs result to
the result word.
