Hi All, I have one question. I am using

GPIO_MODE_MGMT_STD_ANALOG

for all my pin connections. I do not have any digital 1.8V supply in my circuit. The supply range in my circuit is 3 to 5V. I have connected both

io_oeb

and

io_out

pins to ground. Is it ok to connect

io_oeb

to connect to ground instead of vdd?

@naina singhal Do not connect

io_oeb

or

io_out

to 3.3V as these are input to 1.8V devices which may be destroyed with 3.3V. You can connect

io_oeb

and

io_out

to ground (even analog ground). The

GPIO_MODE_MGMT_STD_ANALOG

setting disables the output buffer, you won’t have any conflicts even with

io_oeb

low (output enabled).
