Here's the setup. The intent is as commented.
I will probably compact things once everything is working, but at this
point, I like to keep things separate, and as clear as possible.

Read_Cap_Done:
         ;In bank zero at this point
         bcf     PORTA,Function          ;Set function output as low,

         bsf     STATUS,rp0              ;select bank one
         bsf     TRISB^080h,Capsense     ;Set cap sense pin as input
         bcf     TRISA^080h,Function     ;Set the function pin as output
         bsf     TRISB^080h,Unitid       ;Set Unit ID pin as input
         bcf     STATUS,rp0              ;select bank zero
         bcf     PORTA,Function          ;Set function output as low
         clrwdt                          ;Limits how long we can wait

Read_Function:
         ;btfsc  PORTB,Capsense          ;loop here till low on cap sense pin
         ;goto   Read_Function           ;
