AND
T h i s f u n c t i o n exe c u t e s l o g i c a l A N D
operation on given input signals. The input
signals connected should be of bit input
type only. 4 Bit input pins and 1 Bit output
pin. If all the inputs are ON then the output
is ON, otherwise output is OFF.
19 Byte
5.1
OR
This function executes logical OR operation
on given input signals. The input signals
connected should be of bit input type only. 4
Bit input pins and 1 Bit output pin. If all the
i n p u t s a r e O F F t h e n o u t p u t i s O F F,
otherwise output is ON.
19 Byte
5.2
NOT
T h i s f u n c t i o n exe c u t e s l o g i c a l N OT
operation on given input signal. The input
signal connected should be of bit input type
only. 1 Bit input pin and 1 Bit output pin.
Output is negation of Input given.
10 Byte
5.3
XOR
T h i s f u n c t i o n exe c u t e s l o g i c a l X O R
operation on given input signals. The input
signals connected should be of bit input
type only. 2 Bit input pins and 1 Bit output
pin.If both the inputs are either OFF or ON
then out put is OFF, otherwise output is ON
13 Byte
5.4
NAND
T h i s fu n c tio n exec ut e s l og i c a l NAN D
operation on given input signals. The input
signals connected should be of bit input
type only. 4 Bit input pins and 1 Bit output
pin. If all the inputs are ON then out put is
OFF, otherwise output is ON
19 Byte
5.5
NOR
T h i s f u n c t i o n exe c u t e s l o g i c a l N O R
operation on given input signals. The input
signals connected should be of bit input
type only. 4 Bit input pins and 1 Bit output
pin. If all the inputs are OFF then out put is
ON, otherwise output is OFF
