Operators and symbols.
4.3 Operators and symbols.
They are used to group and operate with different consulting instructions.
The available operators are NOT, AND, OR, XOR. The operators are associated from left
to right and the priorities ordered from the highest to the lowest are: NOT AND XOR OR.
The available symbols are: \, (, ).
NOT
Negates the result of the consultation.
AND
Logic function "AND".
OR
Logic function "OR”.
XOR
Logic "Exclusive OR" function.
\
Line feed.
It is used to write a logic expression in more than one line The following may be programmed:
or also:
( )
Open and close parenthesis.
They help clarify and select the order the logic expression is evaluated.
A consulting instruction consisting of only these two operators always has a value of "1".
NOT I2 = O3
Output "O3" will be active when input I2 is not.
I4 AND I5 = O6
Output "O6" will be active when both inputs (I4, I5) are active.
I7 OR I8 = O9
Output "O9" will be active when either one (or both) inputs are active.
I10 XOR I11 = O12
Output "O12" will be active when both inputs I10 and I11 have different logic states.
DFU MSTROBE AND CPS MFUN* EQ 3 = M1003
DFU MSTROBE \
AND CPS MFUN* EQ 3
= M1003
(I2 OR I3) AND (I4 OR (NOT I5 AND I6)) = O7
( ) = O2
Output O2 will always be high "1".
