14.1 Overview of Word logic instructions
Description
Word logic instructions compare pairs of words (16 bits) and double words (32 bits) bit by bit, according to Boolean logic.
If the result at output OUT does not equal 0, bit CC 1 of the status word is set to
"1".
If the result at output OUT does equal 0, bit CC 1 of the status word is set to "0".
The following word logic instructions are available:
• WAND_W (Word) AND Word
• WOR_W (Word) OR Word
• WXOR_W (Word) Exclusive OR Word
• WAND_DW (Word) AND Double Word
• WOR_DW (Word) OR Double Word
• WXOR_DW (Word) Exclusive OR Double Word

14.2 WAND_W (Word) AND Word
Parameter Data Type Memory Area Description
EN BOOL I, Q, M, L, D Enable input
ENO BOOL I, Q, M, L, D Enable output
IN1 WORD I, Q, M, L, D First value for logic operation
IN2 WORD I, Q, M, L, D Second value for logic operation
OUT WORD I, Q, M, L, D Result word of logic operation
Description
WAND_W (AND Words) is activated by signal state "1" at the enable (EN) input and ANDs the two word values present at IN1 and IN2 bit by bit. The values are interpreted as pure bit patterns. The result can be scanned at the output OUT.
ENO has the same logic state as EN.
Status word
The instruction is executed if I0.0 is "1". Only bits 0 to 3 of MW0 are relevant, the rest of MW0 is masked by the IN2 word bit pattern:
MW0 = 01010101 01010101
IN2 = 00000000 00001111
MW0 AND IN2 = MW2 = 00000000 00000101
Q4.0 is "1" if the instruction is executed.

IN2 WORD I, Q, M, L, D Second value for logic operation
OUT WORD I, Q, M, L, D Result word of logic operation
Description
WOR_W (OR Words) is activated by signal state "1" at the enable (EN) input and ORs the two word values present at IN1 and IN2 bit by bit. The values are interpreted as pure bit patterns. The result can be scanned at the output OUT.
ENO has the same logic state as EN.
Status word
The instruction is executed if I0.0 is "1". Bits 0 to 3 are set to "1", all other MW0 bits are not changed.
MW0 = 01010101 01010101
IN2 = 00000000 00001111
MW0 OR IN2=MW2 = 01010101 01011111
Q4.0 is "1" if the instruction is executed.

14.4 WAND_DW (Word) AND Double Word
Parameter Data Type Memory Area Description
EN BOOL I, Q, M, L, D Enable input
ENO BOOL I, Q, M, L, D Enable output
IN1 DWORD I, Q, M, L, D First value for logic operation IN2 DWORD I, Q, M, L, D Second value for logic operation
OUT DWORD I, Q, M, L, D Result double word of logic
operation
Description
WAND_DW(AND Double Words) is activated by signal state "1" at the enable (EN) input and ANDs the two word values present at IN1 and IN2 bit by bit. The values are interpreted as pure bit patterns. The result can be scanned at the output OUT. ENO has the same logic state as EN.
Status word
The instruction is executed if I0.0 is "1". Only bits 0 and 11 of MD0 are relevant, the rest of MD0 is masked by the IN2 bit pattern:
MD0 = 01010101 01010101 01010101 01010101
IN2 = 00000000 00000000 00001111 11111111
MD0 AND IN2 = MD4 = 00000000 00000000 00000101 01010101 Q4.0 is "1" if the instruction is executed.

14.5 WOR_DW (Word) OR Double Word
Parameter Data Type Memory Area Description
EN BOOL I, Q, M, L, D Enable input
ENO BOOL I, Q, M, L, D Enable output
IN1 DWORD I, Q, M, L, D First value for logic operation IN2 DWORD I, Q, M, L, D Second value for logic operation
OUT DWORD I, Q, M, L, D Result double word of logic
operation
Description
WOR_DW (OR Double Words) is activated by signal state "1" at the enable (EN) input and ORs the two word values present at IN1 and IN2 bit by bit. The values are interpreted as pure bit patterns. The result can be scanned at the output OUT.
ENO has the same logic state as EN.
Status word
The instruction is executed if I0.0 is "1". Bits 0 to 11 are set to "1", the remaining MD0 bits are not changed:
MD0 = 01010101 01010101 01010101 01010101
IN2 = 00000000 00000000 00001111 11111111
