DTMF and Pin problems

Dear Friends
I have connected DTMf to BS and it is working fine. For example when
I generates tone 2 it sends out 0010. The 4 output of the DTMF goes
to pin 8 to 11 of the stamp.
But when I want to check the INC the values are different.
For example[noparse]:D[/noparse]EBUG ?INC give me
5 instead of 0
8 instead of 1
4 instead of 2
12 instead of 3
and so on
Isn't pin 8 to 11 called C, for my example INC????
Does anyone know what I am doing wrong??
Thank you so much

Try swapping the wire on pin 8 with the wire on pin 11 and
the wire on pin 9 with the wire on pin 10.
You may have the pins wired backwards.

what you should see versus what you are seeing:
0 1010 vs 0101
1 0001 vs 1000
2 0010 vs 0100
3 0011 vs 1100
Quick and dirty fix via software:
DEBUG ?INC REV 4
I/O pin 8 is the low order bit of INC, and Q1 is the low order bit of
your DTMF decoder.
