function Man_Receive(var error: byte): byte;

A byte read from the incoming signal.

The function extracts one byte from incoming signal.

Parameters : 

- 

error

: error flag. If signal format does not match the expected, the error flag  

will be set to non-zero. 

To use this function, the user must prepare the MCU for receiving. See
Man_Receive_Init.

var data, error : byte
...

data := 0
error := 0

data := Man_Receive(&error);

if (error <> 0) then

// error handling 

procedure Man_Send_Init();

Nothing.

The function configures Transmitter pin.

Global variables : 

- 

MANRXPIN

: Receive line 

- 

MANRXPIN_Direction

: Direction of the receive pin 

must be defined before using this function.

// Initialize Transmitter:
var MANTXPIN : sbit at PINB.B1;
var MANTXPIN_Direction : sbit at DDRB.B1;
...
Man_Send_Init();
