function Man_Receive_Init(): word;

- 

0

- if initialization and synchronization were successful. 

- 

1

- upon unsuccessful synchronization. 

The function configures Receiver pin and performs synchronization procedure in
order to retrieve baud rate out of the incoming signal.

Note: In case of multiple persistent errors on reception, the user should call this
routine once again or Man_Synchro routine to enable synchronization.

Global variables : 

- 

MANRXPIN

: Receive line 

- 

MANRXPIN_Direction

: Direction of the receive pin 

must be defined before using this function. 

// Initialize Receiver
var MANRXPIN : sbit at PINB.B0;
var MANRXPIN_Direction : sbit at DDRB.B0;
...
Man_Receive_Init();
