* In emac_periph terms, `SIG_GPIO_OUT_IDX` indicates that the EMAC signal cannot be connected
* via the GPIO Matrix (i.e. such connection doesn't exist for the function), so it should
* stay in the default "unconnected state".
*
* Note: `SIG_GPIO_OUT_IDX` is defined for all targets and is usually used to signify "disconnect
* from peripheral signal" (a default unconnected peripheral state).
