Hi Louis,

Asserting the RESET pin on this device will cause it to revert to its default configuration, meaning each port would be configured as an input rather than an output. So, after issuing a reset you should be sure to write to the configuration register to re-define any needed ports to outputs.

If you have any other questions please let us know.

Regards,
Max
