Some questions on NTK WBsensor and on knock detecting with HIP9010

[Marc Reibel]

Hi,

I'm new to the list so I'll introduce myself :
My name is Marc, I come from germany and at the moment I'm doing 
my diploma thesis for MBE. In my spare-time, I'm doing
my own efi-project. It's based on a C167CS microcontroller with
lots of interfacing to the outside world - well, at least to my car :).

Now, let's come to my first question :

I'm following the NTK WB-thread for quite some time now and wondering
if anyone is thinking of implementing a digital driven wb-sensor-
interface like this one :

In accordance to the author, it should be possible to do cylinder-
selective air/fuel-measuring with this device. This would be e neafty 
feature for perfomance enhancements on the engine.

Second Question :

I'm thinking of using the HIP9010 for knock detection. This device
is controlled by SPI-bus. I'm a bit confused about the inverted miso-
line. Can I connect this signal directly to the SPI-interface of my 
controller or do I have to invert it first ?

        mosi-------------miso
HIP9010 sclk-------------sclk C167CS
       /miso-----??------mosi

Thanx a lot,


Marc
