DP83867IS GPIO setting

Hi,

i would like you to confirm how user can change function mode of GPIO_0 and 1.

According to datasheet, there is "GPIO_MUX_CTRL". I confirmed that this register includes several settings, but it seems that this register is NOT included "GPIO" setting itself (No information for register of "GPIO input" or "GPIO output"(This means direction) and  output value(Low/High) of GPIO.).

However, if GPIO function of GPIO_0 and 1 work as only "GPO", my question will be cleared.

Because, if GPIO function of GPIO_0 and 1 work as only "GPO", I can understand that following bitfields are assigned for GPO.

So, could you please confirm whther my above understanding is correct or not ?

Best Regards,

Machida
