Struct PhyCfg

pub struct PhyCfg(/* private fields */);

PHY configuration register (PHYCFGR).

Used for:

• PHY reset.
• PHY operation modes.
• PHY status.

This is used by the Registers::phycfgr and Registers::set_phycfgr methods.

Implementations

impl PhyCfg

pub const RESET: u8 = 184u8

PHY configuration register reset value.

pub const DEFAULT: Self

Default value.

This is the same as default, but as a const value.

Example

use w5500_ll::PhyCfg;

assert_eq!(PhyCfg::DEFAULT, PhyCfg::default());

pub const RST_OFFSET: u8 = 7u8

Bit offset for the RST field.

pub const OPMD_OFFSET: u8 = 6u8

Bit offset for the OPMD field.

pub const OPMDC_OFFSET: u8 = 3u8

Bit offset for the OPMDC field.

pub const DPX_OFFSET: u8 = 2u8

Bit offset for the DPX field.

pub const SPD_OFFSET: u8 = 1u8

Bit offset for the SPD field.

pub const LNK_OFFSET: u8 = 0u8

Bit offset for the LNK field.

pub const RST_MASK: u8 = 128u8

Bit mask for the RST field.

pub const OPMD_MASK: u8 = 64u8

Bit mask for the OPMD field.

pub const OPMDC_MASK: u8 = 56u8

Bit mask for the OPMDC field.

pub const DPX_MASK: u8 = 4u8

Bit mask for the DPX field.

pub const SPD_MASK: u8 = 2u8

Bit mask for the SPD field.

pub const LNK_MASK: u8 = 1u8

Bit mask for the LNK field.

pub const fn rst(self) -> Self

Set the PHY reset bit to 0, resetting the PHY.

pub const fn opmd(&self) -> bool

Get the PHY operation mode.

• true configure PHY with software.
• false (reset value) configure PHY with hardware.

pub const fn hardware_op(self) -> Self

Enable hardware configuration of the PHY operation mode.

This uses the PMODE pins to select the PHY operation mode.

PMODE[2]	PMODE[1]	PMODE[0]	Description
0	0	0	10BT Half-duplex, Auto-negotiation disabled
0	0	1	10BT Full-duplex, Auto-negotiation disabled
0	1	0	100BT Half-duplex, Auto-negotiation disabled
0	1	1	100BT Full-duplex, Auto-negotiation disabled
1	0	0	100BT Half-duplex, Auto-negotiation enabled
1	0	1	Not used
1	1	0	Not used
1	1	1	All capable, Auto-negotiation enabled

Example

use w5500_ll::PhyCfg;

let phy_cfg: PhyCfg = PhyCfg::DEFAULT;
assert!(!phy_cfg.opmd());
let phy_cfg: PhyCfg = phy_cfg.software_op();
assert!(phy_cfg.opmd());
let phy_cfg: PhyCfg = phy_cfg.hardware_op();
assert!(!phy_cfg.opmd());

pub const fn software_op(self) -> Self

Enable software configuration of the PHY operation mode.

Example

use w5500_ll::PhyCfg;

let phy_cfg: PhyCfg = PhyCfg::DEFAULT;
assert!(!phy_cfg.opmd());
let phy_cfg: PhyCfg = phy_cfg.software_op();
assert!(phy_cfg.opmd());

pub const fn opmdc(&self) -> OperationMode

Get the operation mode.

This returns an Err(u8) with the opmdc bits if the opmdc bits do not match a valid operation mode.

Example

use w5500_ll::{OperationMode, PhyCfg};

assert_eq!(PhyCfg::DEFAULT.opmdc(), OperationMode::Auto);

pub const fn set_opmdc(self, mode: OperationMode) -> Self

Set the PHY operation mode.

Setting this will also call PhyCfg::software_op to enable the PHY configuration with the value stored in this register.

Example

use w5500_ll::{OperationMode, PhyCfg};

let phy_cfg: PhyCfg = PhyCfg::DEFAULT;
assert!(!phy_cfg.opmd());
let phy_cfg: PhyCfg = phy_cfg.set_opmdc(OperationMode::PowerDown);
assert!(phy_cfg.opmd());
assert_eq!(phy_cfg.opmdc(), OperationMode::PowerDown);
let phy_cfg: PhyCfg = phy_cfg.set_opmdc(OperationMode::Auto);
assert_eq!(phy_cfg.opmdc(), OperationMode::Auto);

pub const fn dpx(&self) -> DuplexStatus

Get the duplex status.

Example

use w5500_ll::{DuplexStatus, PhyCfg};

let phy_cfg: PhyCfg = PhyCfg::DEFAULT;
assert_eq!(phy_cfg.dpx(), DuplexStatus::Half);

pub const fn spd(&self) -> SpeedStatus

Get the speed status.

Example

use w5500_ll::{PhyCfg, SpeedStatus};

let phy_cfg: PhyCfg = PhyCfg::DEFAULT;
assert_eq!(phy_cfg.spd(), SpeedStatus::Mbps10);

pub const fn lnk(&self) -> LinkStatus

Get the link status.

Example

use w5500_ll::{LinkStatus, PhyCfg};

let phy_cfg: PhyCfg = PhyCfg::DEFAULT;
assert_eq!(phy_cfg.lnk(), LinkStatus::Down);

Trait Implementations

impl Clone for PhyCfg

fn clone(&self) -> PhyCfg

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PhyCfg

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PhyCfg

fn default() -> Self

Returns the “default value” for a type.

impl Display for PhyCfg

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Format for PhyCfg

Available on crate feature defmt only.
