===== IN  =====

===== SYNTAX =====
     = IN(port)

==== PURPOSE ====


The ''IN'' command is used to read a value from a specific input/output (I/O) port.
The ''port'' parameter indicates the exact address of the I/O port from which you want to 
acquire the data. The port address varies depending on the architecture of the 
computer and the connected peripheral. 

When the program encounters the ''IN'' instruction, it stops executing and reads 
the binary value present on the specified port. The value read from the port is 
converted into a numeric format understandable by the program and is assigned 
to the value variable.

The ''IN'' command is often used to read data from sensors connected to I/O ports, 
such as temperature, humidity, light sensors, etc. It can be used to control the 
status of external devices, such as motors, relays, displays, etc. In combination 
with other instructions, the ''IN'' command can be used to implement serial 
communication with other devices.
