5.4 Standard Bitwise Boolean Functions
5.4.1 Boolean AND, boolean OR, boolean exclusive OR, and boolean NOT
AND(_E), OR(_E), XOR(_E), NOT(_E)
(b) The number of pins of variable 's' can be changed in the range from 2 to 27.
(2) OR, OR_E
(a) Performs Boolean OR on bit, word (unsigned)/16-bit string or double word (unsigned)/
32-bit string type data input to variables to bit by bit, and outputs the operation
result from in the same data type as that of variables to .
(Example) Word (unsigned)/16-bit string type data
(b) The number of pins of variable 's' can be changed in the range from 2 to 27.
(3) XOR, XOR_E
(a) Performs Boolean exclusive OR on bit, word (unsigned)/16-bit string or double word
(unsigned)/32-bit string type data input to variables to bit by bit, and outputs the
operation result from in the same data type as that of variables to .
(Example) Word (unsigned)/16-bit string type data
(b) The number of pins of variable 's' can be changed in the range from 2 to 27.
(c) When three or more variables 's' exist, XOR is performed between and first, and
XOR is successively performed between the result and .
When the expression includes , XOR is performed between the result of XOR with
and .
In this manner, XOR is repeated by the number of variables 's' in the order with ,
and so on.
