CPSW Management Data Input/Output (MDIO)

Introduction

The MDIO module implements the MDIO-generic IOCTL commands defined in ENET_MOD_MDIO API set.

MDIO clocks:

• CPSW_CPPI_CLK - CPSW main clock.

Interrupts:

• MDIO_PEND - MDIO interrupt. Peripheral driver must call MDIO_IOCTL_HANDLE_INTR command to handle the MDIO interrupt.

Features:

• MDIO_FEATURE_CLAUSE45 - Clause-45 frame feature.

Compile-time configuration:

• ENET_CFG_MDIO_CLAUSE45 - Clause-45 frame support.

Macro Definition Documentation

MDIO_MAX_PHY_CNT

#define MDIO_MAX_PHY_CNT   (31U)

Maximum number of PHYs supported on MDIO bus.

Enumeration Type Documentation

Mdio_OpMode

enum Mdio_OpMode

MDIO operating mode.

Enumerator
MDIO_MODE_NORMAL	Normal mode
MDIO_MODE_STATE_CHANGE_MON	State change monitor mode
MDIO_MODE_MANUAL	Manual mode (slow GPIO, not used for MDIO PHY operations. Used only during MDIO pins software bit banging)
