GPIO0 can be set to output a pre-divided PLL clock (test only!).
|
|
Enabling this option will configure GPIO0 to output a 50MHz clock.
|
|
In fact this clock doesn't have directly relationship with EMAC peripheral.
|
|
Sometimes this clock won't work well with your PHY chip. You might need to
|
|
add some extra devices after GPIO0 (e.g. inverter).
|
|
Note that outputting RMII clock on GPIO0 is an experimental practice.
|
|
If you want the Ethernet to work with WiFi, don't select GPIO0 output mode for stability.
