MII mode
12.4.1 Code example and explanation
The following example code shows the registers needed to configure the MAC-NET
controller in MII mode.
PORTA_PCR14 = PORT_PCR_MUX(4);//RMII0_CRS_DV/MII0_RXDV
ENET_RCR_CRCFWD_MASK;
12.4.1.1 Hardware implementation
The following figure shows the connection needed from the MAC-NET pins to a generic
Ethernet PHY in MII mode.
In MII mode, Rx and Tx are synchronous to MII0_RXCLK and MII0_TXCLK
respectively. There is no additional requirement from the MAC-NET to synch from the
PHY to the MII/RMII interface. The PHY data sheet must be followed for all electrical
requirements.
