Table 92. Port Configuration Register (Address 16, Hex 10) (Sheet 1 of 2)
1. R = Read Only
2. Default value at the start of auto-negotiation code word transmission.
1. R/W = Read/Write
2. LSHR = Default value is derived from a single device input pin state or a group of device input pin states as
3. The default value of Register bit 16.0 is determined by the G_FX/TP_L pin.
4. The default value of Register bit 16.5 is determined by the PREASEL pin. The BGA15 package does not
5. The BGA15 package does not support fiber. Default for the BGA15 package is 0.
6. NA means the bits do not have a default value and may initially contain any value.

the pin(s) are latched at startup or hardware reset.
If G_FX/TP_L is tied Low, the default value of Register bit 16.0 = 0. If G_FX/TP_L is not tied Low, the
default value of Register bit 16.0 = 1. The BGA15 package does not have a G_FX/TP_L hardware
configuration pin.

1 = Link partner has additional next pages to send
0 = Link partner has not received Link Code Word from
1 = Link partner has received Link Code Word from the
0 = Page sent by the link partner is an unformatted page
1 = Page sent by the link partner is a message page
0 = Link partner cannot comply with the message
1 = Link partner complies with the message
0 = Previous value of the transmitted Link Code Word
1 = Previous value of the transmitted Link Code Word
MP = 1: Code interpreted as message page
MP = 0: Code interpreted as unformatted page
Description
Write as 0, ignore on Read
0 = Normal operation
1 = Force link pass (sets appropriate registers and LEDs
Note: Setting this bit in 100 Mbps mode by-passes the
descrambler lock requirement to establish link and forces
the link to the link-good state. Setting this bit produces
unreliable results if the descrambler is not locked,
0 = Normal operation
1 = Disable twisted-pair transmitter
0 = Normal operation
1 = Bypass scrambler and descrambler
