36.6.1
Name:
Access Type:
• LB: Loopback
Optional. When set, loopback signal is at high level.
• LBL: Loopback Local
When set, connects ETX[3:0] to ERX[3:0], ETXEN to ERXDV, forces full duplex and drives ERXCK and ETXCK_REFCK
with MCK divided by 4.
• RE: Receive Enable
When set, enables the Ethernet MAC to receive data.
• TE: Transmit Enable
When set, enables the Ethernet transmitter to send data.
• MPE: Management Port Enable
Set to one to enable the management port. When zero, forces MDIO to high impedance state.
• CSR: Clear Statistics Registers
This bit is write-only. Writing a one clears the statistics registers.
• ISR: Increment Statistics Registers
This bit is write-only. Writing a one increments all the statistics registers by one for test purposes.
• WES: Write Enable for Statistics Registers
Setting this bit to one makes the statistics registers writable for functional test purposes.
• BP: Back Pressure
If this field is set, then in half-duplex mode collisions are forced on all received frames by transmitting 64 bits of data
(default pattern).
