TX_CLK comes from the RX_CLK pin for jitter
testing in test modes 2 and 3. After exiting the
test mode, a hardware reset or software reset
(register 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, 111b = Reserved.
A write to this register bit does not take effect
until any of the following also occurs:
• Software reset is asserted (register 0.15).
• Restart auto-negotiation is asserted
(register 0.9).
• Power down (register 0.11, 16_0.2)
transitions from power down to normal
operation.
• Copper link goes down.
1b = Manual master/slave configuration.
0b = Automatic master/slave configuration.
A write to this register bit does not take effect
until any of the following also occurs:
• Software reset is asserted (register 0.15).
• Restart auto-negotiation is asserted
(register 0.9).
• Power down (register 0.11, 16_0.2)
transitions from power down to normal
operation.
• Copper link goes down.
After a hardware reset, this bit takes on the
value of pd_config_ms_a.
1b = Manual configure as master.
0b = Manual configure as slave.
A write to this register bit does not take effect

• Software reset is asserted (register 0.15).
• Restart auto-negotiation is asserted

• Power down (register 0.11, 16_0.2)
transitions from power down to normal
operation.
• Copper link goes down.
Register 9.10 is ignored if register 9.12 equals
1b. After a hardware reset, this bit takes on the
value of pd_config_ms_a.
1b = Prefer multi-port device (master).
0b = Prefer single port device (slave).
