The PHY module may be reset by writing a ‘1’ to the
PRST bit in the PHCON1 register (Register 11-1). All
the PHY register contents will revert to their Reset
defaults.

PHY Subsystem Reset
Reset values of the Duplex mode/status bits depend on the connection of the LED to the LEDB pin (see
Section 2.6 “LED Configuration” for additional details).
PRST: PHY Software Reset bit
1 = PHY is processing a Software Reset (automatically resets to ‘0’ when done)
0 = Normal operation
PLOOPBK: PHY Loopback bit
1 = All data transmitted will be returned to the MAC. The twisted-pair interface will be disabled.
0 = Normal operation
Unimplemented: Read as ‘0’
PPWRSV: PHY Power-Down bit
1 = PHY is shut down
0 = Normal operation
Reserved: Maintain as ‘0’
Unimplemented: Read as ‘0’
PDPXMD: PHY Duplex Mode bit
1 = PHY operates in Full-Duplex mode
0 = PHY operates in Half-Duplex mode
Reserved: Maintain as ‘0’
Unimplemented: Read as ‘0’

Unlike other Resets, the PHY cannot be removed from
Reset immediately after setting PRST. The PHY
requires a delay, after which the hardware automati-
cally clears the PRST bit. After a Reset is issued, the
host controller should poll PRST and wait for it to
become clear before using the PHY.
