– Configure EMAC0 and EMAC1 to use internal clocks by setting SDR0_MFR[EnCS]=1 and reset
– Pull down the following signals with 1K resistor: GMCRefClk, GMCCD, GMCTxCLK and GMCRxClk.
– Configure the unused EMACn to use an internal clock by setting SDR0_MFR[EnCS]=1 and reset
– No pull ups or pull downs required.
– Configure the unused EMACn to use an internal clock by setting SDR0_MFR[EnCS]=1 and reset
– Pull down the unused GMCnRxClk signal with a 1K resistor. Pull down is only required if the interface
EMACn by setting EMACn_MR0[SRST]=1.
Pull downs are only required if the interface is never used.
EMACn by setting EMACn_MR1[SRST]=1.
EMACn by setting EMACn_MR1[SRST]=1
is never used.
