Indirect Register 1. MACCN: MAC Control Register
Bit 15:
Reserved. Read = varies; Must write 0b.
Bit 14:
RANDRST: Random Number Generator Reset
Writing a ‘1’ to this bit resets the random number generator within the transmit function.
Bits 13–5:Reserved. Read = varies; Must write 000000000b.
Bit 4:
LOOPBCK: Loopback Mode Enable Bit
Note: MAC Loopback Mode is independent of the physical layer loopback mode.
0: Normal operation.
1: MAC transmit data is internally looped back as MAC receive data.
Bit 3:
TXPAUSE: TX Flow Control Enable Bit (Full-Duplex Only)
0: PAUSE control frames are blocked.
1: PAUSE control frames are allowed to pass through the MAC.
Bit 2:
RXPAUSE: RX Flow Control Enable Bit (Full-Duplex Only)
0: PAUSE control frames received from the physical layer are ignored.
1: PAUSE control frames received from the physical layer are acted upon.
Bit 1:
Reserved. Read = 0; Must write 0b.
Bit 0:
RCVEN: Receive Enable
0: The MAC blocks control frames from reaching the receive interface. The MAC blocks all received
packets from the receive interface.
1: The MAC allows received packets to reach the receive interface.
