SMII Reference Clock for Configurable MAC D:
125 MHz Clock. Must be active to support the
Ethernet statistics registers of CMAC D - even when
the CMAC is configured for GMII Mode.
GMII D Transmit Clock Output: 125 MHz output
clock to which Data, Enable, and Error output signals
are synchronized.
GMII D Transmit Clock: 125 MHz input clock
GMII D Receive Clock: 125 MHz input clock
GMII D Transmit Enable: This active high output
signal is asserted to indicate valid data that is present
on the Data outputs.
GMII D Transmit Error: This active high output
signal is asserted to indicate that a coding violation
exists in the output data stream.
GMII D Receive Data Valid: This active high input
signal is asserted to indicate that valid data is present
on the input data leads.
GMII D Receive Error: This active high input signal is
asserted to indicate that an error was detected in the
incoming data stream.
Transmit Data Port 0D: Bit 0 (LSB) of 8-bit GMII D
Transmit Interface in GMII mode or Bit 0 of 4-bit MII D
Transmit interface.
Receive Data Port 0D: Bit 0 (LSB) of 8-bit GMII D
Receive Interface in GMII mode or Bit 0 of 4-bit MII D
Receive interface.
Transmit Data Port 1D: Bit 1 of 8-bit GMII D
Transmit Interface in GMII mode or Bit 1 of 4-bit MII D
Transmit interface.
Receive Data Port 1D: Bit 1 of 8-bit GMII D Receive
Interface in GMII mode or Bit 1 of 4-bit MII D Receive
interface.
Transmit Data Port 2D: Bit 2 of 8-bit GMII D
Transmit Interface in GMII mode or Bit 2 of 4-bit MII D
Transmit interface.
Receive Data Port 2D: Bit 2 of 8-bit GMII D Receive
Interface in GMII mode or Bit 2 of 4-bit MII D Receive
interface.
