TX FIFO Almost Empty Level

FIGURE 10 PMC-XM SPARTAN3 CHANNEL TX ALMOST EMPTY REGISTER

This register specifies the level at which the transmit FIFO almost empty level will be
asserted. When the number of data words in the transmit FIFO is less than or equal to
this count the almost empty status will be asserted.
