MPC8544E PowerQUICC III Integrated Host Processor Family Reference Manual, Rev. 1
Automatically zero MIB counter values.
0 The user must write the addressed counter zero after a host read.
1 The addressed counter value is automatically cleared to zero after a host read.
This is a steady state signal and must be set prior to enabling the Ethernet controller and must not be
changed without proper care.
MIB counter statistics enabled.
0 Statistics not enabled
1 Enables internal counters to update
This is a steady state signal and must be set prior to enabling the Ethernet controller and must not be
changed without proper care.
Reserved
GMII interface mode. If this bit is set, a PHY with a GMII or RGMII interface is expected to be connected.
If cleared, a PHY with an MII or RMII interface is expected. The user should then set
MACCFG2[I/F Mode] accordingly. The state of this status bit is defined during power-on reset. See
Section 4.4.3, “Power-On Reset Configuration.”
0 MII or RMII mode interface expected
1 GMII or RGMII mode interface expected
Ten-bit interface mode. If this bit is set, ten-bit interface mode is enabled. This bit can be pin-configured
at reset to set or clear. See
0 GMII or MII or RMII mode interface
1 TBI mode interface
Ethernet and FIFO interfaces. RPM and RMM are never set together. This register can be
pin-configured at reset to 0 or 1. See
0 GMII or MII or TBI in non-reduced-pin mode configuration
1 RGMII or RTBI reduced-pin mode
RGMII/RMII 100 mode. This bit is ignored unless SGMIIM, RPM or RMM are set and MACCFG2[I/F
Mode] is assigned to 10/100 (01). If this bit is set, the eTSEC interface is in 100 Mbps speed.
0 RGMII is in 10 Mbps mode;
1 RGMII is in 100 Mbps mode;
Reduced-pin mode for 10/100 interfaces. If this bit is set, a RMII pin interface is expected. Valid only if
FIFM = 0 and TBIM = 0. RPM and RMM are never set together. This register can be pin-configured at
reset to 0 or 1. See
0 MII, RGMII, GMII, TBI, or RTBI mode configuration
1 RMII mode
Serial GMII mode. If this bit is set, a SGMII pin interface is expected to be connected via an on chip
SERDES.
This register can be pin-configured at reset to 0 or 1. See
Section 4.4.3.14, “eTSEC3 Protocol.”
0 SGMII mode disabled. eTSEC connected via a parallel interface.
1 SGMII mode enabled.
Reserved
Reduced-pin mode for Gigabit interfaces. If this bit is set, a reduced-pin interface is expected on either

SGMII is in 100 Mbps mode, and every 10th SGMII Reference clock is used to transfer data
