asserted.
Bits
Description
31:0 EEE RX LPI Transitions
Count of total number of times that the RX LPI indication from the PHY
changed from de-asserted to asserted.
The counter is reset if the Energy Efficient Ethernet (EEE_ENABLE) bit in the
Port x MAC Transmit Configuration Register (MAC_TX_CFG_x) is low.
Type
RO
Default
00000000h

Size:
This register shows the total duration that the PHY has indicated RX LPI.
32 bits
Bits
Description
31:0 EEE RX LPI Time
This field shows the total duration, in microseconds, that the PHY has indi-
cated RX LPI.
The counter is reset if the Energy Efficient Ethernet (EEE_ENABLE) bit in the
Port x MAC Transmit Configuration Register (MAC_TX_CFG_x) is low.
Type
RO
Default
