3.5 19BNotes on Physical Layer Transceiver (PHY) Auto-Negotiation Settings
• The sample program assumes that auto-negotiation mode is used as the PHY link determination method.
• When the partner device is operating in auto-negotiation mode, the link mode is determined according to the priority
levels shown in table 3.3.
Table 3.3 Link Mode Priority Levels
Priority Level Link Mode
High 1 100 Mbps, full-duplex
2 100 Mbps, half-duplex
3 10 Mbps, full-duplex
Low 4 10 Mbps, half-duplex
• The MII/RMII register access timing can be changed by using the following macro definition in the phy.h file. Use
a setting value of 1 or greater.
#define MDC_WAIT 2
• The physical layer transceiver (PHY) reset completion wait duration used by the sample program can be changed by
using the following macro definition in the phy.h file.
#define PHY_RESET_WAIT 0x00020000L
• Auto-negotiation normally takes a few seconds to complete, but the physical layer transceiver (PHY) auto-
negotiation completion wait duration used by the sample program can be changed by using the following macro
definition in the phy.h file.
#define PHY_AUTO_NEGOTIATON_WAIT 0x00800000L
• On the Renesas Starter Kit +(product number: R0K5562N0C000BE) the PHY address is set to 0x1F. The PHY
address used by the sample program can be changed by using the following macro definition in the phy.h file.
#define PHY_ADDR 0x1F
