LPI_LS_TIMER This field specifies the minimum time (in milliseconds) for which the link status from
the PHY should be up (OKAY) before the LPI pattern can be transmitted to the PHY. The MAC does
not transmit the LPI pattern even when the LPIEN bit is set unless the LPI_LS_Timer reaches the
programmed terminal count. The default value of the LPI_LS_Timer is 1000 (1 sec) as defined in
the IEEE standard.(R/W)
LPI_TW_TIMER This field specifies the minimum time (in microseconds) for which the MAC waits af-
ter it stops transmitting the LPI pattern to the PHY and before it resumes the normal transmission.
The TLPIEX status bit is set after the expiry of this timer.(R/W)

LPIINTS When the Energy Efficient Ethernet feature is enabled, this bit is set for any LPI state entry
or exit in the MAC Transmitter or Receiver. This bit is cleared on reading Bit[0] of Register (LPI
Control and Status Register). (RO)
PMTINTS This bit is set when a magic packet or remote wake-up frame is received in the power-
down mode (see Bit[5] and Bit[6] in the PMT Control and Status Register). This bit is cleared
when both Bits[6:5] are cleared because of a read operation to the PMT Control and Status
register. This bit is valid only when you select the optional PMT module during core configuration.
