 		 #129034 - automatic
Responding to: ???'s previous message

//Multiprocessor Communication Registers
unsigned char *SADDR;
unsigned char *SADEN;

//Setup Multiprocessor communication
SADDR = (unsigned char *)0xA9;
SADEN = (unsigned char *)0xB9;

*SADDR = 0x3e;
*SADEN = 0xff;

So manually setting and resetting RB8 works very well. However I cannot get the automatic part of this working.

My understanding of this is that (slave)SADDR | SADEN form's a value of ones and 0's. The 0's represent "don't care" bits.

The 1's that the (master)SADDR |SADEN form must match the 1's that the slave's form.

In my example I made SADDR and SADEN the same value for both the master and the slave, however RB8 still dictates weather or not the value is received.
