TP Signal on 7i92

Probably one for PCW
Is there any useful information available on TP<0> & TP<1> pads.

Cheers

Currently they time the RX and TX data transfer overhead:

EtherRecv2Mem
        sta     SetTP0
        lda     recvfcount      ; already doing a multi frame recv,
        jmpnz   recvframe       ; so skip the prelims   

.......

recvdone
        lwi     1
        addto   recvpktcount
        lwi     MinusSix                ;adjust for CRC and 2 byte offset
        addto   recvpktsize
        sta     ClrTP0
        ret

EtherSendFromMem
        sta     SetTP1
        lda     sendpktsize             
        add     threeloc

.......

        lwi     1
        addto   sendpktcount  
        sta     ClrTP1
        ret     




 

So basically just a square wave on each physical pad ?

I was thinking it might have been some serial debug info.

Well it's whatever the last debug usage was...
