Other Parts Discussed in Thread: AM1808

Please let me know is it possible to configure AM1808 GPIO's in Hi-Z mode. If possible pls direct me to the documentation if anything is available. Since i could not find such information in the AM1808 TRM

AM1808 does not usually haunt this space - this forum. Better targeting your post is likely to yield improved results...

As a general rule - placing a GPIO into, "Open Drain" mode - usually will accommodate your desire...

Hello Sudarshan,

There is no option to configure the GPIOs in Hi-Z mode. You can configure it either as input or output.

As the above post recommends, you can configure the GPIOs as output and left it open drain.

Most GPIOs go through the pinmux where mux select 0 is tri-stated hi-Z.
