Expand description

Accesses PHY registers.

This trait is used to implement the unified interface to access C22 and C45 PHY registers.

§Examples

fn link_change_notify(dev: &mut Device) {
    // read C22 BMCR register
    dev.read(C22::BMCR);
    // read C45 PMA/PMD control 1 register
    dev.read(C45::new(Mmd::PMAPMD, 0));

    // Checks the link status as reported by registers in the C22 namespace
    // and updates current link state.
    dev.genphy_read_status::<phy::C22>();
    // Checks the link status as reported by registers in the C45 namespace
    // and updates current link state.
    dev.genphy_read_status::<phy::C45>();
}
