10.7.2.28 Port x EEE TX LPI Request Delay Register (EEE_TX_LPI_REQ_DELAY_x)
Register #:
Port0: 0443h
Port1: 0843h
Port2: 0C43h
Size:
32 bits
This register contains the amount of time, in microseconds, the MAC must wait after the TX FIFO is empty before invok-
ing the LPI protocol.
Note: The actual time can be up to 1 us longer than specified.
Note: A value of zero is valid and will cause no delay to occur.
Note: If the TX FIFO becomes non-empty, the timer is restarted
Bits
