How to write session registers in NT3H1101

[burakkabasakal]

Hello, 

Here I want to work with Pass-through mode. Here I need to modify the PTHRU_ON_OFF bit. But I have a problem to write this bit. 

I am able to read session registers. It's sequence is readed from datasheet. It's

start '0' -

write(FEh) -

write(00h (for NC_reg)-

stop

start '1'

read

stop

However , when I trying to writing in same place, I have a problem. I am doing also same sequence in datasheet, its

start '0' -

write(FEh)

write(00h (for NC_reg)-

write(02h)(for FD_ON also tried others byte)

write(01h)(to enable this bit)

stop

Can you help me in this problem. Whats my error here.

Hi,

Would you please specify what was the problem during I2C write? no ACK? Please kindly clarify.

Thanks for your patience!

Have a great day,
Kan
