Bits Field Mode HW Rst SW Rst Description
15:13 Test Mode R/W 0x0 Retain
TX_CLK comes from the RX_CLK pin for jitter testing in test modes
2 and 3. After exiting the test mode, hardware reset or software
reset (register 0_0.15) should be issued to ensure normal
operation.
A restart of auto-negotiation clears these bits.
000b = Normal mode.
001b = Test Mode 1 - Transmit waveform test.
010b = Test Mode 2 - Transmit jitter test (master mode).
011b = Test Mode 3 - Transmit jitter test (slave mode).
100b = Test Mode 4 - Transmit distortion test.
101b, 110b, and 111b = Reserved.

R/W 0x0 Update
A write to this register bit does not take effect until any of the
following also occurs:
• Software reset is asserted (register 0_0.15).
• Restart auto-negotiation is asserted (register 0_0.9).
• Power down (register 0_0.11, 16_0.2); transitions from power
down to normal operation and the copper link goes down.
1b = Manual master/slave configuration.
0b = Automatic master/slave configuration.

R/W Update
A write to this register bit does not take effect until any of the
following also occurs:
• Software reset is asserted (register 0_0.15).
• Restart auto-negotiation is asserted (register 0_0.9).
• Power down (register 0_0.11, 16_0.2); transitions from power
down to normal operation and the copper link goes down.
1b = Manual configure as master.
0b = Manual configure as slave.
10 Port Type R/W Update
A write to this register bit does not take effect until any of the
following also occurs:
• Software reset is asserted (register 0_0.15).
• Restart auto-negotiation is asserted (register 0_0.9).
• Power down (register 0_0.11, 16_0.2); transitions from power
down to normal operation and the copper link goes down.
Register 9_0.10 is ignored if register 9_0.12 is equal to 1b.
1b = Prefer multi-port device (master).
0b = Prefer single port device (slave).
