CM8880/MT8880 transceiver

[shufa]

Hello everyone ,

I don't know how to interface CM8880 with a PIC16F84A . I don't understand parallax dialect from CM8880 pdf and I don't know if I 'translated' it corectly in MPASM dialect.
I wrote this, but I dont know if it is good.
I hope someone can help me

This is the schematic diagram for my project > https://i27.tinypic.com/veprae.jpg. As you can see, I know how to hardware interface a PIC16F84A and a MT8880. . My questions refeer to software interface. I don't know if my code is correct. Please someone help me.

What exactly is your problem? Have you actually built the circuit?
If you have have you tried your code and found a specific problem?
I think you have had no answers because you have not asked a specific question, try your code and if it does not work then tell us what it is or is not doing.

Shufa,
I haven't looked much at your code, but I noticed on your schematic that you've left the MCLR pin of the PIC floating. You need to tie it to Vdd with a 10K resistor or erratic operation will result.
