Protocol I2C not reading 16bits address

[Joao Paulo]

Hi,

I have a small problem with I2C master tab.

I am at waveforms 3.17.1 and I am trying to use the protocol tab with DD device.

My intent is to read an address on a device, which is 16bits wide address. It happens that I can only read the first address 0000h. Even if I change the SubAddress to 0001h, it will still read 0000h. 

I made it work in the custom tab, but not in this. Is it supposed to be this way?

 

Thanks,

Hi @Joao Paulo

The sub/register address is not read but written by the master.
