Other Parts Discussed in Thread: TCA6416
Hi,
I used a TCA6416A in project. When I read register or input port register, there is a phenomenon I want to confirm.
When I use read method in Figure.32- master only send 7bit addr+Read(1) bit, TCA6416A didn't send any data out and ACK.
But when I used Figure.31 way to read any register or use WRITE command, TCA6416 could feedback data or ACK. Than use Figure.32 way to read, TCA6416A could feedback ACK and data.
So I was wondering, is that true, I have to read with Figure 31 way or write, then read with Figure 32 way could be used after?
Thank you!
