6.6
Depending on the application, bits in three of the PHY
module’s registers may also require configuration.
The PHCON1.PDPXMD bit partially controls the
device’s half/full-duplex configuration. Normally, this bit
is initialized correctly by the external circuitry (see
Section 2.6 “LED Configuration”). If the external
circuitry is not present or incorrect, however, the host
controller must program the bit properly. Alternatively,
for an externally configurable system, the PDPXMD bit
may be read and the FULDPX bit be programmed to
match.
For proper duplex operation, the PHCON1.PDPXMD
bit must also match the value of the MACON3.FULDPX
bit.

This bit is ignored.
When PHCON1<8> = 0 and PHCON1<14> = 0:
1 = Transmitted data will only be sent out on the twisted-pair interface
0 = Transmitted data will be looped back to the MAC and sent out on the twisted-pair interface

If using half duplex, the host controller may wish to set
the PHCON2.HDLDIS bit to prevent automatic
loopback of the data which is transmitted.
The PHY register, PHLCON, controls the outputs of
LEDA and LEDB. If an application requires a LED
configuration other than the default, PHLCON must be
altered to match the new requirements. The settings for
LED operation are discussed in Section 2.6 “LED
Configuration”. The PHLCON register is shown in
Register 2-2 (page 9).
