3.6.1.10 Handshake Control Bit

Set the B13 to 0 if the command is sent to the MagicScan controller. Keep this bit at high when not used.

The demo program of handshaking is given as follows:

WORD pic_control(WORD i)

{

WORD j; if ((inport(wAddrCtrl)&0x04)==0)

{

outport(wAddrCtrl,0xffff); /* send a recovery to PIC */

} j=0; while ((inport(wAddrCtrl)&0x04)==0)

{

j++;


} i = i & 0xDFFF; /* set pic low !! */ outport(wAddrCtrl,i); j=0; while ((inport(wAddrCtrl)&0x04)!=0)

{

j++;


} outport(wAddrCtrl,(WORD)(i | 0x2000)); /* set pic high !! */ j=0; while ((inport(wAddrCtrl)&0x04)==0)

{

j++;

if (j>65530) return(AdControllerError); //time out

} return(NoError);

}
