ADT7420 giving acks dor read and writes, but donot put any data to bus on read

Category: Hardware
Product Number: ADT7420

Hi,

I'm writing the driver for it in VHDL.

I am getting the acks from the device, but no data on SDA during read. It is 00h(completely pulled low by device). Logic analyser capture is attached.

Any suggestions on what to check as I have verified basic timing, commands, etc.
